The highest dipole moment is for:

Options

  1. ACHCl ₃
  2. BCH ₄
  3. CCCl ₄
  4. DCH ₂ Cl ₂

Correct answer

D. CH ₂ Cl ₂

Step-by-step solution

The molecules CH ₄ and CCl ₄ have highly symmetrical tetrahedral geometries, resulting in a net dipole moment of zero. For CH ₂ Cl ₂ and CHCl ₃ , the net dipole moment is the vector sum of the individual C-H and C-Cl bond dipoles. In CH ₂ Cl ₂ , the resultant of the two C-Cl bond dipoles and the two C-H bond dipoles reinforce each other more effectively than the bond dipoles in CHCl ₃ . The experimental dipole moments are: CH ₄ = 0 D CCl ₄ = 0 D CHCl ₃ = 1.04 D CH ₂ Cl ₂ = 1.60 D Thus, CH ₂ Cl ₂ has the highest dip
