Chemistry · CHEMICAL BONDING AND MOLECULAR STRUCTURE

Consider the following statements regarding the polarity of molecules: (A) \( \text{CCl}_4 \) has polar \( \text{C}-\text{Cl} \) bonds but its net dipole moment is zero. (B) The net dipole moment of \( \text{H}_2\text{O} \) is \( 1.85\text{ D} \) because of its bent structure. (C) \( \text{CHCl}_3 \) has a net dipole moment of zero due to tetrahedral symmetry. (D) In \( \text{BeF}_2 \), the two equal \( \text{Be}-\text{F} \) bond dipoles cancel each other because the molecule is linear. Which of the above statements are correct?

1. A
   (A), (B) and (C) only
2. B
   (A), (B) and (D) only
3. C
   (B) and (C) only
4. D
   (C) and (D) only
