Vedclass · Answer

(C) The complex $[Co(en)_2Cl_2]Cl$ is an octahedral complex ($d^2sp^3$ hybridization).It exhibits geometrical isomerism due to the presence of $cis$ and $trans$ forms.The $cis$-isomer is optically active and shows optical isomerism.Ionic isomerism occurs when the counter ion in the coordination compound is a potential ligand that can exchange places with a ligand in the coordination sphere. In $[Co(en)_2Cl_2]Cl$,the chloride ion is the counter ion,but there is no other isomer possible where the $Cl^-$ ion enters the coordination sphere and a ligand from the coordination sphere becomes the counter ion without changing the chemical formula or structure in a way that qualifies as ionic isomerism. Thus,statement $(c)$ is false.

In the coordination compound $[Co(en)_2Cl_2]Cl$,which of the following statements is false?
