Vedclass · Answer

(D) racemic mixture is formed by mixing equimolar amounts of enantiomers ($d$ and $l$ forms). For this to occur,the complex must be optically active (chiral). $1$. $[Ni(DMG)_2]$ is a square planar complex and is achiral. $2$. $cis-[Cu(gly)_2]$ is achiral due to the presence of a plane of symmetry. $3$. $[Zn(en)(gly)]^+$ is achiral as it is a tetrahedral complex. $4$. $trans-[Co(gly)_3]$ is an octahedral complex that exhibits optical isomerism (it exists as $d$ and $l$ enantiomers). Therefore,mixing the $d$ and $l$ forms of $trans-[Co(gly)_3]$ in a $1:1$ ratio results in a racemic mixture.

In which case is a racemic mixture obtained upon mixing its mirror images ($d$ and $l$ forms) in a $1:1$ molar ratio?
