Vedclass · Answer

(B) The complex $[Co(en)_2Cl_2]^+$ exhibits geometrical isomerism and optical isomerism.$1$. Geometrical Isomers: It has $2$ geometrical isomers,namely $cis$ and $trans$.$2$. Optical Isomers: The $trans$ isomer is achiral (optically inactive) due to the presence of a plane of symmetry.The $cis$ isomer is chiral and exists as a pair of enantiomers ($d$ and $l$ forms).Therefore,the total number of isomers is $1$ (trans) + $2$ (cis enantiomers) = $3$ isomers.
