The Total solution for NCERT class 6-12
Draw all the isomers (geometrical andoptical) of:
(i) [CoCl_2(en)_2]_+
(ii) [Co(NH_3)Cl(en)_2]_2+
(i) [CoCl2(en)2]+ Geometricalisomerism
Opticalisomerism Since only cis isomer isoptically active, it shows optical isomerism.
In total, three isomers are possible.
(ii) [Co(NH3)Cl(en)2]2+
Geometrical isomerism
Optical isomerism Since only cis isomer isoptically active, it shows optical isomerism.
(iii) [Co(NH3)2Cl2(en)]+
