Question

What molecules have nonpolar covalent bonds?

Answer 1

Homonuclear diatomic molecules for a start.

Explanation:

Any homonuclear diatomic molecule, `H_2`, `Li_2`, `N_2`, `O_2`, `C_2`, `X_2`, clearly possesses a non-polar `"element-element"` bond.

Most organic molecules, which feature `C-C`, and `C-H` bonds are also non-polar.
