$[Co(CN)_5(NC)]^{3-}$

Vedclass · Answer

(B) $1$. $[CoCl_2(en)_2]$ shows $cis$ and $trans$ geometrical isomerism.$2$. $[Co(CN)_5(NC)]^{3-}$ is an octahedral complex of the type $[MA_5B]$,which does not exhibit geometrical isomerism.$3$. $[Co(NH_3)_3(NO_2)_3]$ shows $fac$ (facial) and $mer$ (meridional) isomerism,which are types of geometrical isomerism.$4$. $[Co(NH_3)_4Cl_2]^+$ shows $cis$ and $trans$ geometrical isomerism.Therefore,the correct option is $B$.

Indicate the complex or complex ion which does not show any geometrical isomerism:
