NH₃ has a bond angle less than CH₄ because:

Practice MCQ for SSC, UPSC, RRB Exams

A. Lone pair–bond pair repulsion is less A.

B. Bond pair–bond pair repulsion is greater B.

C. Lone pair–bond pair repulsion is greater C.

D. It is planar D.

Correct Answer: C সঠিক উত্তর: C

Explanation ব্যাখ্যা

The correct answer is C) Lone pair–bond pair repulsion is greater.
In NH₃, the nitrogen atom has one lone pair and three bonding pairs of electrons. The lone pair-bond pair repulsion is greater than the bond pair-bond pair repulsion, which causes the bond angle (~107°) to be less than the tetrahedral angle (109.5°) found in CH₄.
