Question

For the given complex $\left[CoC{l}_2\right(en\left)\right(N{H}_3{)}_2{]}^{+}$, the number of geometrical isomers and the number of optical isomers respectively are:

• A. $2,2$
• B. $2,0$
• C. $2,4$
• D. $0,2$

Answer 1

The correct option is A $2,2$

The complex is of the form $\left[M\right(AA\left)X_2{Y}_2\right]$, so it will show cis and trans isomers. Out of these cis isomer is optically active and shows $d$ and $l$.
