The dipoles cancel out each other, depicted in a VSEPR diagram. When determining the polarity of a molecule, we use 2 methods: 1: Electrongativity, 2: Symmetry of molecule. Electronegativity: Electronegativity of a compound can be calculated by subtracting the element with the highest electronegativity with the lowest. Electronegativity can be found on the periodic table: Compounds with an ...
The dipole moment of a "C-H" bond is probably 0.34 D. > We often say that a "C-H" bond is nonpolar because the electronegativities of "C" and "H" are so close to each other. However, the values are "C = 2.55" and "H = 2.20". The difference corresponds to 3% ionic character, so a "C-H" bond should have a small dipole moment. From experimental IR intensities of methane, we can infer that µ_text ...
"CH"_4 is nonpolar, both within each bond and as an overall molecule. Polarity can either be within a bond, when one atom "hogs" the electrons more than the other, or in the overall molecule, when all the electrons tend to "group" to one side of the molecule but not the other. A dipole simply refers to the two poles of a magnet. Similar to that, a chemical bond with a dipole suggests that one ...
Even if the molecule had polar C-H bonds, the symmetry of molecule would cause the bond dipoles to cancel. The molecule would still be nonpolar. It is a blob with no positive or negative ends. The only forces left to consider are London dispersion forces. In a nonpolar molecule, electrons are always moving.
