$Pb^{2+}$

Vedclass · Answer

(D) The correct answer is $(d)$ $Pb^{2+}$.Ammonia $(NH_3)$ acts as a ligand and forms stable complexes with transition metal ions like $Ag^{+}$,$Cu^{2+}$,and $Cd^{2+}$ due to the availability of vacant $d$-orbitals and their ability to accept lone pairs of electrons.$Pb^{2+}$ is a post-transition metal ion that does not readily form stable ammine complexes in aqueous solution compared to transition metal ions,as it lacks the specific electronic configuration and $d$-orbital characteristics required for such complexation.
