Assertion : NH(3) is less basic than PH(...

Assertion : `NH_(3)` is less basic than `PH_(3)`
Reason: Nitrogen is more electronegative than phosphorus.

A

Both A and R are true and R is the correct explanation of A

B

Both A and R are true but R is false

C

A is true but R is false

D

Both A and R are false.

Text Solution
