In case of nitrogen, NCl3 is possible but no NCl5 while in case of phosphorus, PCl3 as well as PCl5 are possible. It is due to :
A
Availability of vacant d-orbital in P but not in N.
B
Lower electronegativity of P then N.
C
Lower tendency of H bond formation in P than N.
D
Occurrence of P in solid while N in gaseous state at room temperature.
Answer
Availability of vacant d-orbital in P but not in N.
Explanation
Solution
In phosphorous the vacant 3 d-orbitals are available. So it can increase its covalence beyond three.
