Assertion(A) - `BF_3` molecule is planar but `NF_3` is pyramidal
Reason( R )-N atom is smaller than B

A

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

B

If both assertion and reason are correct , but reason is not the correct explanation of the assertion.

C

If assertion is correct, but reason is incorrect .

D

If both assertion and reason are incorrect.

Text Solution

Verified by Experts

The correct Answer is:
b
Correct explanation . In `BF_(3)` , B is `sp^(2)` -hybridised .
Hence , it is triangular planar . In `NF_(3)`, N is `sp^(3)` - hybridized with one position occupied by a lone

Hence , it is pyramidal
