Given below are two statements :

Statement I : \([Co(NH_3)_6]^{3+}\) is a homoleptic complex whereas \([Co(NH_3)_4Cl_2]^+\) is a heteroleptic complex.

Statement II : Complex \([Co(NH_3)_6]^{3+}\) has only one kind of ligands but \([Co(NH_3)_4Cl_2]^+\) has more than one kind of ligands.

In the light of the above statements, choose the correct answer from the options given below:

1. Statement I is false but Statement II is true.

2. Both Statement I and Statement II are true.

3. Both Statement I and Statement II are false.

4. Statement I is true but Statement II is false.

Best answer

Answer: 2. Both Statement I and Statement II are true.

Key idea: a homoleptic complex has only one kind of ligand; a heteroleptic complex has more than one kind.

\(\mathrm{[Co(NH_3)_6]^{3+}}\) has only \(\mathrm{NH_3}\) (homoleptic). \(\mathrm{[Co(NH_3)_4Cl_2]^+}\) has \(\mathrm{NH_3}\) and \(\mathrm{Cl^-}\) (heteroleptic). Both statements are true: option 2.
