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) \[\ce{[Cr(NH3)5Cl]}\]

Short/Brief Note

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 \[\ce{[Co(en)2Cl2]^+}\]
