# Why are most organic molecules non-polar?

Most hydrocarbons are nonpolar, because $\text{C-H}$ bonds are nonpolar.
But there are many more organic compounds that contain functional groups like $\text{Cl}$, $\text{OH}$, $\text{COOH}$, $\text{C≡N}$, ${\text{NH}}_{2}$, ${\text{NO}}_{2}$, etc.
Atoms like $\text{O}$, $\text{N}$, and $\text{Cl}$ are all more electronegative than $\text{C}$, so they all have polar bonds.
