Q. In case of nitrogen, $NCl_{3}$ is possible but not $NCl_{5}$ while in case of phosphorus, $PCl_{3}$ as well as $PCl_{5}$ are possible. It is due to
A) Lower electronegativity of P but not in N
B) Lower tendency of H bond formation in P than N
C) Availability of vacant $d$-orbital in P but not in N
D) Occurrence of P in solid while N in gaseous state at room temperature
Explanation
(c)
Nitrogen does not have $d$-orbitals
