Which one of the following is expected to exhibit optical isomerism?
1 trans - \(\left[\mathrm{Co}(\mathrm{en})_{2} \mathrm{Cl}_{2}\right]\)
2 trans - \(\left[\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{2} \mathrm{Cl}_{2}\right]\)
Cis isomer can be resolved in two forms if molecule is \(\mathrm{M}(\mathrm{AA})_{2} \mathrm{~B}_{2}\). where (AA) is bidentate ligand.

\(\left[\mathrm{Co}(\mathrm{en})_{3}\right]^{3+}\) ion is expected to show
1 two optically active isomers: \({\rm{d}}\,\,{\rm{and}}\,\,{\rm{l}}\) forms
2 \({\rm{d, l}}\) and meso forms
3 four optically active isomers: cis, \({\rm{d}}\,\,{\rm{and}}\,\,{\rm{l}}\) isomers and trans \({\rm{d}}\,\,{\rm{and}}\,\,{\rm{l}}\) isomers
4 none of these
Explanation:
\({\left[ {{\text{Co(en}}{{\text{)}}_{\text{3}}}} \right]^{{\text{3 + }}}}\) ion due to absence of one of the symmetry of elements it has two \(d\) and \(l\) optically active forms.

Which of the following complexes exhibit optical isomerism?
1 trans-tetraamminedithiocyanatochromium (III) ion
2 cis-diamminedicarbonatocobalt (III) ion
3 trans-diaminedicarbonatocobalt (III) ion
4 cis-glycinatoplatinum (II)
Explanation:
trans octahedral complexes do not show optical isomerism therefore,(1) and (3) are not correct. Glycinato ligand is bidentate with both ends comprising of different elements bonding with central atom Pt, cannot show optical isomerism.
