Q:

which of the following molecule contains a nonpolar covalent bond?

A) Br2 B) CO2
C) CCl4 D) CO
 
Answer & Explanation Answer: A) Br2

Explanation:

Br-Br.

The other options all include a significantly more electronegative atom (the oxygens and the chlorine), so those bonds are all polar covalent.
