The highest dipole moment is for:
Options
- ACHCl ₃
- BCH ₄
- CCCl 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
