Polar Molecules Tutorial: How to determine polarity in a molecule
 
10:36
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.

*** 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?

This chemistry video tutorial provides a basic introduction into dipole dipole forces of attraction. A dipole is a molecule that contains a permanent separation of charge. One side of the molecule may have a partial positive charge while the other side may contain a partial negative charge. The dipole dipole interactions arises when the partial positive charge of one molecule is attracted to the partial negative charge of another molecule. Therefore, dipole dipole interactions are intermolecular forces. This video contains plenty of examples of dipole dipole attractions. Every polar molecule contains a dipole moment.

Molecular Shape and Polarity: How to determine whether a molecule will be polar or nonpolar
 
07:29
http://purplebonding.com A polar molecule is a molecule that has poles -- a positive and negative pole to be exact. To determine whether a molecule is polar, you first need to determine if the bonds between the atoms are polar. Next, you use VSEPR, valence shell electron pair repulsion theory, to predict the shape of the molecule. Some shapes will cause the dipoles to cancel out, much as in an even-sided tug-of-war. Some shapes will be asymmetrical, and the dipoles will not cancel out. These factors explain why carbon dioxide CO2 is nonpolar, whereas water H2O is. Watch the video to learn more about determining molecular polarity.

Atomic Hook-Ups - Types of Chemical Bonds: Crash Course Chemistry #22
 
09:46
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?

Ionic Bonds, Polar Covalent Bonds, and Nonpolar Covalent Bonds
 
11:00
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.

Polar and Non Polar Covalent Molecules, Polar vs. Nonpolar - CLEAR & SIMPLE
 
14:18
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.
