प्रश्न

Assertion: Complexes of MX6 and MX5L type (X and L are unidentate) do not show geometrical isomerism.

Reason: Geometrical isomerism is not shown by complexes of coordination number 6.

पर्याय

उत्तर

Assertion is true, reason is false.

Explanation:

Complexes like MX6 and MX5L have symmetrical ligand arrangements, so they don't exhibit geometrical isomerism. However, coordination number 6 complexes can show geometrical isomerism when they have different ligands arranged in various spatial configurations.
