Geometrical isomerism

Vedclass · Answer

(C) The complex $[Co(NH_3)_4Cl_2]^+$ exhibits geometrical isomerism. It exists in two forms: $cis$ and $trans$. The $cis$-isomer has the two $Cl^-$ ligands adjacent to each other,while the $trans$-isomer has the two $Cl^-$ ligands opposite to each other. These two isomers have different physical properties,including color,due to their different spatial arrangements.

The existence of two different colored complexes of $[Co(NH_3)_4Cl_2]^+$ is due to which of the following?
