Question

Why Pcl 5 exist but ncl does not exist

Answer 1

I guess your question​ is why doesn't NCl5 exists.

Well in PCl5 the hybridization is sp3d, since phosphorus has d orbitals it can go to a higher oxidation state of +5, while nitrogen has no d orbitals hence NCl5 cannot be formed.

Answer 2

Answer:

Explanation:P can form PCl5 because of the vacant d- orbital in its balance shell.

But NCl5 on the other hand, cannot exist because of no vacant d-orbital in its balance shell.

Pls mark it as the brainliest answer.
