Question

nitrogen does not form pentahalide like phosphorus?

Answer 1

 
Formation of pentahalides requires sp³d hybridization of central atom. This can be obtained by transfer of electrons from central atom to empty d-orbitals in excited state.
As nitrogen has no d orbitals in its valence shell, it cannot undergoes sp3d hybridization and hence cannot form pentahalides .

Answer 2

Answer:

Heya babes here's ur answer dear

Nitrogen forms pentoxide, but does not form pentachloride. ... Nitrogen does not form pentachloride, because it doesn't possess d-orbital. Formation of any pentahalides requires sp3d hybridisation of the central atom. This is obtained by the excitement of electrons of the central atom to empty d orbital.
