Question

In which of the following, racemic mixture is obtained on mixing its mirror images in 1:1 molar ratio?

• A. $\left[Cr\right(en{)}_3{]}^{3+}$
• B. $\left[Ni\right(DMG{)}_2]$
• C. $Cis-\left[Cu\right(Gly{)}_2]$
• D. All of the above

Answer 1

The correct option is A $\left[Cr\right(en{)}_3{]}^{3+}$

$\left[Cr\right(en{)}_3{]}^{3+}$ gives racemic mixture on mixing its mirror images in $1:1$ molar ratio.
