  • Identify the optically active compounds from the following: - (i) [CO(en)_{3}]^{3+} (ii) trans-[Co(en)_{2}Cl_{2}]^{+} (iii) cis-[Co(en)_{2}Cl_{2}]^{+} (iv) [Cr(NH_{3})_{5}Cl]

Identify the optically active compounds from the following: -

(i) [Co(en)_{3}]^{3+}

(ii) trans-[Co(en)_{2}Cl_{2}]^{+}

(iii) cis-[Co(en)_{2}Cl_{2}]^{+}

(iv) [Cr(NH_{3})_{5}Cl]

Answers (1)

Option (i) and (iii) are the correct answers.

(a,c) [Co(en)_{3}]^{3+} and cis-[Co(en)_{2}Cl_{2}]^{+} are optically active compounds because their mirror images are non-superimposable isomers.

Non-superimposable isomers of [Co(en)_{3}]^{3+}

Non-superimosable isomers of [Co(en)_{2}Cl_{2}]^{+}

Hence, (i) and (iii) are correct choices.
