While phosphorus forms PC l(5), nitrogen...

While phosphorus forms `PC l_(5)`, nitrogen does not form `NC l_(5)` because

A

Nitrogen is more electronegative than phosphorus

B

Nitrogen atom is smaller than phosphorus

C

The ionisation energy of nitrogen is greater than that of phosphorus

D

Unlike phosphorus, nitrogen has no 'd' orbital in its valence shell

Text Solution

Verified by Experts

The correct Answer is:
D
Nitrogen does not form `NC l_(5)` due to the absence of d-orbital in its configuration
`""_(7)N=1s^(2),2s^(2),2p^(3),""_(15)P=1s^(2),2s^(2),2p^(6),3s^(2),3p^(3),3d^(0)`.
