Why are pentahalides of `P,As,Sb` and `Bi` are more covalent than trihalides?

Text Solution

Verified by Experts

In pentahalides, the oxidation state is `+5` and in trihalides, the oxidation state is `+3`. Since the metal ion with a high charge has more polarizing power, pentahalides are more covalent than trihalides.
