Question

Which of the following coordination entity form racemic mixture when mixed in equimolar concentration?

• A. $\left[Cr\right(OX{)}_3{]}^{3-}$
• B. $\left[Co\right(en{)}_{2}C{l}_2{]}^{+}$
• C. $\left[Co\right(en)C{l}_4{]}^{-}$
• D. All

Answer 1

The correct option is D All

All the co-ordination entities are able to form racemic mixture because all they can form enantiomers so possibility of racemic mixture is 100% will rotate and inverts into one of the enantiomers forms racemic mixture.
