PCl5 exists but Ncl5 does not why?

N does not have the provision of vacant d orbital but P has as its principal quatum no. is 3...so its subahell extend to d...which is vacant.
Thus P is able to form 5 bonds with Cl but N cannot.

Pcl5 exist as
Electronic configuration of P(15): 1s2 2s2 2p6 3s2 3p3
After 3p 3d orbital comes so PCl 5 can exisit
But NCl5 does not exist because
Electronic configuration of N(7): 1s2 2s2 2p3
Now 2 energy level does not contain d orbital so NCl5 does not exist
Hybridization of PCl5 is sp3d
But N doest not have d orbital so cant have hybridization sp3d
