Assertion . The bond anlge of `PBr_(3)` is greater than that of `PH_(3

1.	Assertion . The bond anlge of `PBr_(3)` is greater than that of `PH_(3)` but bond angle of `NBr_(3)` is less than that of `NH_(3)`. Reason .Electronegativity of phosphorus atom is less than that of nitrogen .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.
Answer» Correct Answer - b Correct explanation. The truth of assertion is not due to difference in the electronegativities of N and P but due to difference in electronegativity of H and Br (in `NH_(3) and NBr_(3))` and due to reaonance in ` PBr_(3)` but no resonance in `PH_(3)`
