PC l_5 exists but NC l_5 does not because - Vidyadip

MCQ

$PC{l_5}$ exists but $NC{l_5}$ does not because

✓
Nitrogen has no vacant $d-$ orbitals
B
$NC{l_5}$ is unstable
C
Nitrogen atom is much smaller
D
Nitrogen is highly inert

✓

Answer

Correct option: A.

Nitrogen has no vacant $d-$ orbitals

(a) Nitrogen does not have vacant $‘d’-$ orbitals so it can’t have $+5$ oxidation state

i.e. the reason $PC{l_5}$ exists but $NC{l_5}$ does not.
