Question

The dipole moments of ,  and  are in the order

Canvas Classes · Accepted Answer

Step 1 — Analyse each molecule:

: Tetrahedral, all C–H bonds equivalent → bond dipoles cancel → μ = 0

: Tetrahedral, all C–Cl bonds equivalent → bond dipoles cancel → μ = 0

(chloroform): Tetrahedral but asymmetric (3 Cl + 1 H) → bond dipoles do NOT cancel → μ ≠ 0 (≈ 1.87 D)

Step 2 — Order:
