Question

Given below are two statements:\ Statement I : $\left[\mathrm{Co}\left(\mathrm{NH}_3ight)_6ight]^{3+}$ is a homoleptic complex whereas $\left[\mathrm{Co}\left(\mathrm{NH}_3ight)_4 \mathrm{Cl}_2ight]^{+}$is a heteroleptic complex.\ Statement II : Complex $\left[\mathrm{Co}\left(\mathrm{NH}_3ight)_6ight]^{3+}$ has only one kind of ligands but $\left[\mathrm{Co}\left(\mathrm{NH}_3ight)_4 \mathrm{Cl}_2ight]^{+}$has more than one kind of ligands.\ In the light of the above statements, choose the correct answer from the options given below:

Professor PC Thomas Classes · Answer

(a) : Complexes in which a metal is bound to only one kind of donor groups e.g., $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]^{3+}$ are known as homoleptic. Complexes in which a metal is bound to more than one kind of donor groups, e.g., $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_4 \mathrm{Cl}_2\right]^{+}$are known as heteroleptic.
