Question
Identify the optically active compounds from the following:
(i) \[\ce{[Co(en)3]^{3+}}\]
(ii) \[\ce{[trans - [Co(en)2Cl2]^+}\]
(iii) \[\ce{cis - [Co(en)2Cl2]^+}\]
(iv) \[\ce{[Cr(NH3)5Cl]}\]

Solution
(i) \[\ce{[Co(en)3]^{3+}}\]
(iii) \[\ce{cis - [Co(en)2Cl2]^+}\]
Explanation:
\[\ce{[Co(en)3]^{3+}}\] and \[\ce{[Co(en)2Cl2]^{2+}}\] are optically active compounds because their mirror images are non-superimposable isomer.
Non – superimposable isomers of \[\ce{[Co(en)3]^{3+}}\]
Non – superimosable isomers of \[\ce{[Co(en)2Cl2]^+}\]
