As we learned in concept

Optical Isomerism -

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

-

 

 [Co(NH_{3})Cl_{3}]^{0} does not show optical isomerism because all of its possible structures have symmetry.

 


Option 1)

\left [ Co(NH_{3})_{3}Cl_{3} \right ]^{0}

This option is correct.

Option 2)

\left [ Co(en)Cl_{2}(NH_{3})_{2} \right ]^{+}

This option is incorrect.

Option 3)

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

This option is incorrect.

Option 4)

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

This option is incorrect.
