    Draw all the isomers (geometrical and optical) of:
    () [CoCl2(en)2]+
    () [Co(NH3)Cl(en)2]2+
    () [Co(NH3)2Cl2(en)]+
    () [CoCl2(en)2]+
    () [Co(NH3)Cl(en)2]2+
    () [Co(NH3)2Cl2(en)]+
    Ans : null () [CoCl2(en)2]+ Geometrical isomerism



    Optical isomerism Since only cis isomer is optically active, it shows optical isomerism.



    In total, three isomers are possible.
    () [Co(NH3)Cl(en)2]2+

    Geometrical isomerism



    Optical isomerism Since only cis isomer is optically active, it shows optical isomerism.


    () [Co(NH3)2Cl2(en)]+


    () [CoCl2(en)2]+ Geometrical isomerism



    Optical isomerism Since only cis isomer is optically active, it shows optical isomerism.



    In total, three isomers are possible.
    () [Co(NH3)Cl(en)2]2+

    Geometrical isomerism



    Optical isomerism Since only cis isomer is optically active, it shows optical isomerism.
