Indicate the complex/complex ion which did not show any geometrical isomerism :

Multiple Choice Options

  • A [CoCl2(en)2]
  • B [Co(CN)5(NC)]3 −-
  • C [Co(NH3)3(NO2)3]
  • D [Co(NH3)4Cl2]+

Step-by-Step Verified Solution

(a) [CoCl2(en)2] show Cis-trans isomerism

(b) [Co(CN)5(NC)]3 −- can't show G.I.

(3) [Co(NH3)3(NO2)3] show fac & mer isomerism

(d) [Co(NH3)4Cl2]+ show cis & trans isomerism
