Question

Both geometrical and optical isomerism are shown by:

• A. $\left[Co\right(en{)}_{2}C{l}_2{]}^{+}$
• B. $\left[Co\right(N{H}_3{)}_{5}Cl{]}^{2+}$
• C. $\left[Co\right(N{H}_3{)}_{4}C{l}_2{]}^{+}$
• D. $\left[Cr\right(ox{)}_3{]}^{3-}$

Answer 1

The correct option is A $\left[Co\right(en{)}_{2}C{l}_2{]}^{+}$

Both geometrical and optical isomerism is shown by $\left[Co\right(en{)}_{2}C{l}_2{]}^{+}$.


No isomerism is shown by $\left[Co\right(N{H}_3{)}_{5}Cl{]}^{2+}$.

$\left[Co\right(N{H}_3{)}_{4}C{l}_2{]}^{+}$ shows geometrical isomerism.

$\left[Cr\right(ox{)}_3{]}^{3-}$ shows optical isomerism.
