Polar & Non-Polar Molecules: Crash Course Chemistry #23
*** PLEASE WATCH WITH ANNOTATIONS ON! SOME INACCURACIES IN GRAPHICS ARE NOTED AND CORRECTED IN ANNOTATIONS. THANKS! *** Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or non-polar, which describes a kind of symmetry - not just of the molecule, but of the charge. In this edition of Crash Course Chemistry, Hank comes out for Team Polar, and describes why these molecules are so interesting to him. You'll learn that molecules need to have both charge asymmetry and geometric asymmetry to be polar, and that charge asymmetry is caused by a difference in electronegativities. You'll also learn how to notate a dipole moment (or charge separation) of a molecule, the physical mechanism behind like dissolves like, and why water is so dang good at fostering life on Earth. -- Table of Contents Charge Assymetry & Geometric Asymmetry 01:33 Difference in Electronegatives 01:49 Hank is Team Polar 00:33 Dipole Moment 03:49 Charge Separation of a Molecule 04:12 Like Dissolves Like 04:41 Water is Awesome 05:10 -- Want to find Crash Course elsewhere on the internet?

Ionic Bonds, Polar Covalent Bonds, and Nonpolar Covalent Bonds
This organic chemistry video tutorial explains how to identify a bond as an ionic bond, polar covalent bond, or a nonpolar covalent bond. Ionic bonds usually consist of metals and nonmetals where as covalent bonds consists of nonmetals. In a nonpolar covalent bond, electrons are shared equally and the electronegativity difference between the two atoms is 0.4 or less. For polar covalent bonds, the electrons are shared unequally between the two atoms and the electronegativity difference is defined to be 0.5 or more.

Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry #22
Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike with human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about. If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law. -- Table of Contents Bonds Minimize Energy 01:38 Covalent Bonds 03:18 Ionic Bonds 05:37 Coulomb's Law 05:51 -- Want to find Crash Course elsewhere on the internet?

Chemistry: What is a Covalent Bond? (Polar and Nonpolar)
Chemistry: What is a Covalent Bond? (Polar and Nonpolar) Covalent bonds are one of the 3 main types of intramolecular forces, along with ionic bonds and metallic bonds. Covalent bonds are the result of atoms sharing their valence electrons. Covalent bonds can be polar or nonpolar, depending on the electronegativies of the atoms involved in the bond. We show five examples of covalent bonds using Lewis dot structure notation: HF, CO2, H2, H2O and CCl4.

Polar Covalent Bonding
Follow us at: https://plus.google.com/+tutorvista/ Check us out at http://chemistry.tutorvista.com/organic-chemistry/polar-covalent-bond.html Polar Covalent Bond The polar covalent bond, called a polar bond for short, is a variation on the standard covalent bond. It is defined by a difference in electronegativity values of 0.4 or greater, the meaning of which shall be made clear below. All covalent bonds are polar to some extent unless the bond is between two atoms of the same element. It is best to start with a review of the standard covalent bond. This is the sharing of electrons between two elements in order to have 8 electrons in the outer shell. The only exception to this is Hydrogen, which is stable with 2 electrons in its outer shell. The structure of each element gives it a different electronegativity value. This value is effectively the strength of the pull of that atom's nucleus on the electrons around it. The higher the value the greater the pull. A covalent bond is electrons moving around two atoms; they are being shared. It is the difference between the electronegativity values that determines which atom gets the larger share of the electron's time. If the electrons spend more of their time around one atom out of the pair then that region will have more negative charge than the other atom. Carbon to Carbon Bond The first example is the standard Carbon to Carbon bond such as occurs in the alkane molecules. We are just considering the bond that these two atoms share without regard for any other bonds that this pair of atoms may be involved in. First we can draw the two atoms as shown below. The pair of electrons that form the bond are drawn between them. The values written below the atoms are from the electronegativities table. The difference is calculated which in this case is zero. A polar covalent bond occurs every time Hydrogen bonds with Nitrogen, Oxygen or Fluorine as these are the three elements with the highest electronegativity values. They all have a difference of 0.9 or greater with Hydrogen. These bonds are called polar because of the different charges. These act like magnets and so polar molecules are pulled toward each other, with opposite charges attracting. The polar covalent bond is commonplace. Water is a liquid at room temperature because of these bonds. Ammonia (NH3) dissolves readily in water because of these bonds. This model even explains why water expands as it freezes. A polar covalent bond involving Hydrogen with any of the three most electronegative elements of Nitrogen, Oxygen and Fluorine is especially strong and is called a Hydrogen bond.

How Does Water Bond - Covalent Bonds | Chemistry for All | FuseSchool
Learn the basics about the covalent bonding of water, when learning about covalent bonding within properties of matter. Water is made from one oxygen atom and two hydrogens. The oxygen has 6 electrons in its outer shell, but it really wants to have 8 to have a full shell. The hydrogens have one outer shell electron, but want to have two. The atoms share their electrons, forming covalent bonds. So all three atoms have full outer shells, and create a water molecule. Water has two covalent bonds. In water, the bonding electrons spend most of their time nearer the oxygen atom, because it is more ELECTRONEGATIVE. This means that it is electron withdrawing. As the negatively charged electrons are nearer the oxygen atom, the oxygen atom becomes a little bit negative itself, while the hydrogens become a little positive. This is called delta positive and delta negative. Water doesn’t just have any old covalent bonds; it has what we call POLAR COVALENT bonds and is a POLAR molecule. This is really important as it affects how water behaves and reacts with other elements. SUBSCRIBE to the Fuse School YouTube channel for many more educational videos.

Polar Covalent Bonds and Nonpolar Covalent bonds, Ionic Bonding - Types of Chemical Bonds
This chemistry video tutorial provides a basic introduction into the types of chemical bonds such as polar covalent bonds, nonpolar covalent bonds and ionic bonds. It discusses the difference between ionic bonding and covalent bonding. Ionic bonds can be identified by looking for a metal combined with a nonmetal. Covalent bonds typically occur among 2 or more nonmetals. Covalent bonding involves a sharing of electrons and ionic bonding forms as a result of a transfer of electrons from the metal to the nonmetal producing ions with opposite charge which are attracted to each other. The electrostatic force of attraction produces the ionic bond that holds the cations and anions together. Polar covalent bonds have unequal sharing of electrons between the atoms where as nonpolar covalent bonding have a relatively equal sharing of electrons between the atoms attached to the bond. Polar covalent bonds typically have an electronegativity difference of 0.5 or more where as nonpolar covalent bonds have a value difference of 0.4 or less. This video contains plenty of examples and practice problems.

Ionic Compounds - Metals and Nonmetals 4. Molecular Compounds - 2 or More Nonmetals 5. Polar Covalent Bonding - Unequal Sharing of Electrons 6. Nonpolar Covalent Bonds - Equal Sharing of Electrons 7. Polarized Compounds - Dipole Moment and Charge Separation 8. Electronegativity and Charge Distribution 9. Metal Cations vs Nonmetal Anions
Ionic vs. Molecular
To see all my Chemistry videos, check out http://socratic.org/chemistry How can you tell the difference between compounds that are ionic and molecular (also known as covalent)? It has to do with the elements that make them up: ionic compounds are made of metals and nonmetals, and molecular (or covalent) compounds are made of nonmetals. We'll learn how they bond differently: in covalent compounds, the atoms share electrons, and in ion compounds, atoms steal electrons and then opposite charges attract. Ionic and molecular (covalent) compounds also look different at the microscopic level: covalent and molecular compounds exist in molecules, while ionic compounds are organized in lattice structures.

Polar and Non Polar Covalent Molecules, Polar vs. Nonpolar - CLEAR & SIMPLE
CLEAR & SIMPLE - What is the difference between polar and nonpolar molecules? Check out this video on Molecular Polarity which makes this EASY. Polar and Non Polar Covalent Molecules - This video explains how to determine if a molecule is polar or non polar. I show you how, based on symmetry alone, a molecule can be determined to polar or non polar. Although I show you the shapes of the molecules, it is important for you to be able to classify the shapes according to the VSEPR Theory, so please learn your shapes. The degree of polarity can be determine to a certain extent by the differences in electronegativity, but I don't cover that in this video. Best wishes in learning.

Polar Molecules Tutorial: How to determine polarity in a molecule
This video looks at how to determine polarity in a molecule by understanding how the bond polarities, molecule shape, and outside atoms influence polarity using bond polarity vector addition. This includes a flow chart that guides you through the various decisions needed to determine if a molecule is polar or not. Wikipedia 1/1/2018: In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have a geometry which is asymmetric in at least one direction, so that the bond dipoles do not cancel each other. While the molecules can be described as "polar covalent", "nonpolar covalent", or "ionic", this is often a relative term, with one molecule simply being more polar or more nonpolar than another. However, the following properties are typical of such molecules. A molecule is composed of one or more chemical bonds between molecular orbitals of different atoms. A molecule may be polar either as a result of polar bonds due to differences in electronegativity as described above, or as a result of an asymmetric arrangement of nonpolar covalent bonds and non-bonding pairs of electrons known as a full molecular orbital. Polar molecules[edit] The water molecule is made up of oxygen and hydrogen, with respective electronegativities of 3.44 and 2.20. The dipoles from each of the two bonds (red arrows) add together to make the overall molecule polar. A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H2O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other. The dipoles do not cancel out resulting in a net dipole. Due to the polar nature of the water molecule itself, polar molecules are generally able to dissolve in water. Other examples include sugars (like sucrose), which have many polar oxygen–hydrogen (−OH) groups and are overall highly polar. If the bond dipole moments of the molecule do not cancel, the molecule is polar. For example, the water molecule (H2O) contains two polar O−H bonds in a bent (nonlinear) geometry. The bond dipole moments do not cancel, so that the molecule forms a molecular dipole with its negative pole at the oxygen and its positive pole midway between the two hydrogen atoms. In the figure each bond joins the central O atom with a negative charge (red) to an H atom with a positive charge (blue). The hydrogen fluoride, HF, molecule is polar by virtue of polar covalent bonds – in the covalent bond electrons are displaced toward the more electronegative fluorine atom. Ammonia, NH3, molecule the three N−H bonds have only a slight polarity (toward the more electronegative nitrogen atom). The molecule has two lone electrons in an orbital, that points towards the fourth apex of the approximate tetrahedron, (VSEPR). This orbital is not participating in covalent bonding; it is electron-rich, which results in a powerful dipole across the whole ammonia molecule. Resonance Lewis structures of the ozone molecule In ozone (O3) molecules, the two O−O bonds are nonpolar (there is no electronegativity difference between atoms of the same element). However, the distribution of other electrons is uneven – since the central atom has to share electrons with two other atoms, but each of the outer atoms has to share electrons with only one other atom, the central atom is more deprived of electrons than the others (the central atom has a formal charge of +1, while the outer atoms each have a formal charge of −​1⁄2). Since the molecule has a bent geometry, the result is a dipole across the whole ozone molecule. When comparing a polar and nonpolar molecule with similar molar masses, the polar molecule in general has a higher boiling point, because the dipole–dipole interaction between polar molecules results in stronger intermolecular attractions. One common form of polar interaction is the hydrogen bond, which is also known as the H-bond. For example, water forms H-bonds and has a molar mass M = 18 and a boiling point of +100 °C, compared to nonpolar methane with M = 16 and a boiling point of –161 °C. Nonpolar molecules[edit] A molecule may be nonpolar either when there is an equal sharing of electrons between the two atoms of a diatomic molecule or because of the symmetrical arrangement of polar bonds in a more complex molecule. Not every molecule with polar bonds is a polar molecule. Carbon dioxide (CO2) has two polar C=O bonds, but the geometry of CO2 is linear so that the two bond dipole moments cancel and there is no net molecular dipole moment; the molecule is nonpolar.

Why is water a polar molecule? High school chemistry.
GET MORE AMAZING VIDEOS: https://viziscience.com Watch the new version of this video - https://www.youtube.com/watch?v=DvIaDY6PLHQ&feature=youtu.be The water molecule is a polar molecule due to the **unequal sharing of electrons** in the bonds and also the ****bent shape***** of the molecule. ***** The shape of the molecule is an important factor why water is polar. If the bond angle is set to 180º, even if the bonds are polar, the whole molecule will still be non-polar. But the shape of water molecule is BENT with an angle of about 105°, so that's why the forces are distributed unequally and the forces cannot cancel out ******** (Please note that this video is created to help you visualize the concept of why water is a polar molecule. It does not represent how electrons actually travel - please read Heisenberg's Uncertainty Theory. Also, the shape of a water molecule is a tetrahedral geometry and you have to visualize in 3d how the bonds are formed. Last of all, an electron could be thought of as a wave. So, instead of thinking of an electron as a little orange dot, think of it as a force spreading over a volume, taking the shape of the orbital of its energy level.) Why is water a polar molecule? Water is a polar molecule because one side is positively charged and one side is negatively charged. Oxygen has 6 valence electrons and hydrogen has 1. Oxygen combines with 2 hydrogens in order to make 1 water molecule. Thus, oxygen would have 8 valence electrons as a result of the bonding and hydrogen would have 2. The water molecule fulfills the octet rule. However, oxygen attracts electrons more strongly than hydrogen. This causes the electrons to move closer to oxygen. Because of this, the oxygen ends up having a slightly negative charge and the hydrogen atom ends up with a slightly positive charge. A water molecular has a polar covalent bond. This is called a separation of charges, one end of the molecule is slightly negatively charged and the other end is slightly positively charged. Polarity means having electricity charge and that's why the water molecular is said to be a polar molecule.

Polar vs Nonpolar vs Ionic Bonds (Covalent vs Ionic Bonds) CLEAR & SIMPLE
Polar Covalent, Nonpolar Covalent and Ionic Bonds - This is a quick video describing the differences between Ionic Bonds and Covalent bonds (Polar Covalent Bonds and Nonpolar Covalent Bonds). This video demonstrates how these bonds can be classified based on electronegativity. This video also defines what a polar bond is, relative to an ionic bond. Bond polarity is a difficult topic, so I try extra hard to make it clear. I really think you can watch the video, then totally understand the topic. I have another video which explains the polarity of molecules. Molecular polarity depends on bond polarity to a certain degree. Check it out if you like this video.
