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.
