Ammonia acts as a ligand. Discuss.

Text Solution

Verified by Experts

Ammonia `(overset(* *)(NH_(3)))` has lone pair of electrons on the nitrogen atom and is a Lewis base. Since it can easily donate the electron pair, ammonia acts as a ligand and forms co-ordination bonds with electron deficient species.
