  • Solve it, Optical isomerism is not shown by the complex :(Ox = Oxalate & en = ethylenediamine)

Optical isomerism is not shown by the complex :

 

(Ox = Oxalate & en = ethylenediamine)

  • Option 1)

    \left [ Cr (ox)_{3} \right ]^{3-}

  • Option 2)

    \left [ Co(en)_{2} \right Cl_{2} ]^{+} (Cis-form)

  • Option 3)

    \left [ Co(en)_{2} \right Cl_{2}]^{+} (trans-form)

  • Option 4)

    \left [ Cr(en)_{3} \right ]^{3+}

As we learnt in 

Optical Isomerism -

Optical isomers are mirror images that cannot be suprimposed on one another

-

 

 Trans \left [ Co\left ( en \right )_{2}Cl _{2}\right ]^{+} structure

Clearly, we can superimpose its mirror image on itself. So it won't show optical isomerism.

 


Option 1)

\left [ Cr (ox)_{3} \right ]^{3-}

This answer is incorrect

Option 2)

\left [ Co(en)_{2} \right Cl_{2} ]^{+} (Cis-form)

This answer is incorrect

Option 3)

\left [ Co(en)_{2} \right Cl_{2}]^{+} (trans-form)

This answer is correct

Option 4)

\left [ Cr(en)_{3} \right ]^{3+}

 

This answer is incorrect
