Assertion (A) : `PH_(3)` is more basic than `NH_(3)`
Reason (R) : EN of N is more than that of P

PH_3 is less basic than NH_3 .

PH_3 is less basic than NH_3 .

Assertion (A) : P_(2)O_(3) is more basic than N_(2)O_(3) Reason (R) : Metallic nature of the central atom increases down the group

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

Assertion (A) : P_(4) is more reactive than N_(2) Reason (R) : P-P bonds are relatively weaker than N-=N
