Q:

The carbon tetrachloride molecule (CCl4) is

A) a nonpolar molecule with polar bonds B) a nonpolar molecule with nonpolar bonds
C) a polar molecule with polar bonds D) a polar molecule with nonploar bonds
 
Answer & Explanation Answer: A) a nonpolar molecule with polar bonds

Explanation:

The four bonds of carbon tetrachloride (CCl4) are polar, but the molecule is nonpolar because the bond polarity is cancelled by the symmetric tetrahedral shape. Hence, making the net dipole as zero and molecule as non-polar.

 

When other atoms substitute for some of the Cl atoms, the symmetry is broken and the molecule becomes polar.
