Question

Given below are two statements: Statement I: [Co(NH3)6]3+[Co(NH_3)_6]^{3+} is a homoleptic complex, whereas [Co(NH3)4Cl2]+[Co(NH_3)_4Cl_2]^+ is a heteroleptic complex. Statement II: Complex [Co(NH3)6]3+[Co(NH_3)_6]^{3+} has only one kind of ligand but [Co(NH3)4Cl2]+[Co(NH_3)_4Cl_2]^+ has more than one kind of ligands. In light of the above statements, choose the correct answer from the options given below:

A

Both Statement I and Statement II are False.

B

Statement I is True but Statement II is False.

C

Statement I is false but Statement II is True.

D

Both Statement I and Statement II are True.

Step-by-Step Solution

According to the nomenclature of coordination compounds, complexes in which a metal is bound to only one kind of donor group are known as homoleptic complexes (e.g., [Co(NH3)6]3+[Co(NH_3)_6]^{3+} where only NH3NH_3 ligands are present). Complexes in which a metal is bound to more than one kind of donor group are known as heteroleptic complexes (e.g., [Co(NH3)4Cl2]+[Co(NH_3)_4Cl_2]^+ where both NH3NH_3 and ClCl^- ligands are present). Since Statement II provides the correct reasoning that perfectly aligns with the definitions applied in Statement I, both statements are true.
