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.

In Br2, two of the same atoms, pull on each side of the bond is equal making it as non-polar.

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