Assertion : In `NH_(3), N "is " sp^(3)` hybridised but bond angle is `107^(@)`.
Reason : Shape of `NH_(3)` molecule is trigonal pyramidal.

A

If both assertion and reason are true and reason is the correct explanation of assertion.

B

If both assertion and reason are true but reason in not the correct explanation of assertion.

C

If assertion is true but reason is false.

D

If both assertion and reason are false.

Text Solution

Verified by Experts

The correct Answer is:
B
`NH_(3)` molecule has three bond pairs and one lone pair of electrons.
Lone pair - bond pair repulsions are greater than bond pair - bond pair repulsions and hence result in deviation from ideal tetrahedral angle ` 109. 5^(@)`.
