Vedclass · Answer

(C) An ion is optically active if it lacks a plane of symmetry or a center of inversion.$I$: This is the $trans-[Co(en)_2Cl_2]^+$ isomer. It has a plane of symmetry and is optically inactive.$II$: This is the $cis-[Co(en)_2Cl_2]^+$ isomer. It lacks a plane of symmetry and is optically active.$III$: This is $[Co(en)_3]^{3+}$. It is a propeller-shaped complex that lacks a plane of symmetry and is optically active.$IV$: This is the $trans-[Co(en)_2Cl_2]^+$ isomer (same as $I$). It has a plane of symmetry and is optically inactive.Therefore,$II$ and $III$ are optically active.

Column-$I$	Column-$II$
$(a) [Pt(NH_3)_3Cl]Br$	$(P) \text{Coordination isomerism}$
$(b) [Cr(NH_3)_5(NCS)]^{+2}$	$(Q) \text{Ionisation isomerism}$
$(c) [Co(H_2O)_6]Cl_3$	$(R) \text{Linkage isomerism}$
$(d) [PtCl_4][Pt(NH_3)_4]$	$(S) \text{Hydrate isomerism}$
