Assertion . BF_(3) molecular is planar but NF_(3) pyramidal Reason . N

1.	Assertion . BF_(3) molecular is planar but NF_(3) pyramidal Reason . N atom is smaller than B
Answer» If both assertion and REASON are correct, and reason is the correct EXPLANATION of the assertion. If both assertion and reason are correct , but reason is not the correct explanation of the assertion. If assertion is correct, but reason is incorrect . If both assertion and reason are incorrect. Solution :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
