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:
A
Statement I is true but Statement II is false.
B
Statement I is false but Statement II is true.
C
Both Statement I and Statement II are true.
D
Both Statement I and Statement II are false.
Detailed Solution
$[Co(NH_3)_6]^{3+}$ has only one type of ligand ($NH_3$), so it is a homoleptic complex.
$[Co(NH_3)_4Cl_2]^+$ has more than one type of ligand ($NH_3$ and $Cl^-$), so it is a heteroleptic complex.
So both Statement I and Statement II are true.
