Vedclass · Answer

(B) The complex $[CrCl_2(en)(NH_3)_2]$ is of the type $M(AA)X_2Y_2$,where $M = Cr$,$AA = en$,$X = Cl$,and $Y = NH_3$.This complex exhibits $3$ geometrical isomers:$1$. One $cis$ isomer where the two $Cl$ atoms are adjacent.$2$. Two $trans$ isomers where the two $Cl$ atoms are opposite to each other,but the relative positions of $NH_3$ and $en$ differ.Thus,the total number of geometrical isomers is $3$.

The number of geometrical isomers of $[CrCl_2(en)(NH_3)_2]$,where $en = \text{ethylenediamine}$,is
