A covalent bond involves the sharing of electrons between two atoms, but they typically are not shared equally. The difference in electronegativity between the two atoms defines whether a bond is classified as nonpolar covalent or polar covalent.

Sections:
00:00 - Defining electronegativity with Pauling scale
00:30 - Comparing carbon and oxygen
01:20 - Partial charges in polar covalent bonds
02:35 - Nonpolar covalent bond: carbon-carbon
03:29 - Carbon-hydrogen bond: borderline polarity
04:13 - Carbon-oxygen bond: polar covalent
05:00 - Cutoff for polar vs nonpolar covalent bonds
05:25 - Note on electronegativity scales
05:45 - Example: oxygen-hydrogen bond analysis
