Question

Which can exist both as diastereoisomer and enantiomer?

• A. $\left[Pt\right(en{)}_3{]}^{4+}$
• B. $\left[Pt\right(en{)}_{2}ClBr{]}^{2+}$
• C. $\left[Ru\right(N{H}_3{)}_{4}C{l}_2{]}^0$
• D. $[PtC{l}_{2}B{r}_2{]}^0$

Answer 1

The correct option is A $\left[Pt\right(en{)}_3{]}^{4+}$

It exists as lis trans which is diastereomer and its cis form is optically active and exits as enantiomer also,where as only exists as enantiomers.
