Vedclass · Answer

(C) Complexes are formed by the donation of a lone pair of electrons from a ligand to a metal ion. In $NH_3$,the nitrogen atom has one lone pair of electrons,which allows it to act as a ligand. In the formation of the $NH_4^+$ ion,this lone pair is donated to a proton $(H^+)$. Consequently,the $NH_4^+$ ion does not possess any lone pair of electrons to donate to a central metal ion,and therefore,it cannot act as a ligand or form complexes.

Ammonia acts as a ligand but ammonium ion does not form complexes because
