Question

PCl5 is possible but NCl5 does not exist, because (A) in N, d-subshell is absent (B) ionization energy of N is very high (C) it does not like Cl (D) none of these

Tardigrade Admin · Accepted Answer

Due to the absence of d-orbital, N cannot expand its octet, hence it cannot from NCl5

Q. $PC l_{5}$ is possible but $NC l_{5}$ does not exist, because

in N, d-subshell is absent

ionization energy of N is very high

it does not like Cl

none of these

Due to the absence of d-orbital, N cannot expand its octet, hence it cannot from $NC l_{5}$
