1.	Statement-1. BF_(3) molecule is planar whileNF_(3) is pyramidal. Statement-2. N atom is smaller than B .
Answer» Statement-1 is TURE , Statement-2 is Ture , Statement-2 is a correct explanation for Statement-1. Statement-1 is Ture , Statement-2 is Ture , Statement-2 is nota correct explanation for Statement-1. Statement-1 is True , Statement-2 isFalse . Statement-1 is FALSE, Statement-2 is True. Solution :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.)
