Among the following, the molecule with the lowest dipole moment is

Options

  1. ACHCl ₃
  2. BCH ₃ Cl
  3. CCH ₂ Cl ₂
  4. DCCl ₄

Correct answer

D. CCl ₄

Step-by-step solution

CCl ₄ has lowest (zero) dipole moment. This is due to its symmetrical tetrahedral structure. Due to which dipole moment of one bond is cancelled by opposite dipole moment of the other three bonds.
