In `NH_(3)`, bond angle is less than tetrahedral bond angle due to ________.

A

Bond pair repulsion

B

Lone pair repulsion

C

Bond pair-lone pair repulsion

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
In `NH_3`, although the central atom N is `sp^3` hybridised, the bond angle is `107^@` (instead of `109^@28.`). The decrease in bond angle is due to repulsion between the lone pair of electrons on N-atom and bond pair of electrons between N and H atoms.
