Standard Books Chemistry Dipole Moment MCQ Question with Solution

The dipole moments of CCl₄, CHCl₃ and CH₄ are in the order

A

CH₄ = CCl₄ < CHCl₃

B

CHCl₃ < CH₄ = CCl₄

C

CH₄ < CCl₄ < CHCl₃

D

CCl₄ < CH₄ < CHCl₃

Option A

Dipole moment (μ) is zero for symmetrical molecules i.e., μ_CCl₄ = μ_CH₄ = 0 but μ_CHCl₃ > 0. Therefore, CH₄ = CCl₄ < CHCl₃.
