Statement-1. `BF_(3)` molecule is planar while ` NF_(3)` is pyramidal.

1.	Statement-1. `BF_(3)` molecule is planar while ` NF_(3)` is pyramidal. Statement-2. N atom is smaller than B .A. Statement-1 is Ture , Statement-2 is Ture , Statement-2 is a correct explanation for Statement-1.B. Statement-1 is Ture , Statement-2 is Ture , Statement-2 is not a correct explanation for Statement-1.C. Statement-1 is True , Statement-2 is False .D. Statement-1 is False, Statement-2 is True.
Answer» Correct Answer - b Correct explanation . In `BF_(3)` , hybridisation of B atom is `sp^(2)` while iin `NF_(3)` , hybridisation o N atom is `sp^(3)` (of course , N atom is smaller than B because along a period the size decreasses.)
