The stability of +5 oxidation state decr...

The stability of `+5` oxidation state decreases down the group `15` of the periodic table.Explain this observation giving appropriate reasons.

Text Solution

Verified by Experts

This is on account of inert pair effect as a result of which valence s-electrons `(ns^(2)p^(3))` are reluctant to take part in bond formation.
