Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

The product obtained by${\mathrm{S}}_{\mathrm{N}}2$reaction of haloalkane having chirality at the reactive site shows inversion of configuration because incoming nucleophile attacks from opposite side of the leaving group.
Enantiomers are non superimposable mirror images of each other.  A racemic mixture shows zero optical rotation due to external compensation of optical rotation of the mixture.
