STANDARD Chemistry Dipole Moment MCQ Question
Type: MCQ-conceptual-Medium-Class 11
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
Correct Answer
Option A
Detailed Explanation
Dipole moment (μ) is zero for symmetrical molecules i.e., μ_CCl₄ = μ_CH₄ = 0 but μ_CHCl₃ > 0. Therefore, CH₄ = CCl₄ < CHCl₃.
