The incorrect statement regarding chirality is :

The incorrect statement regarding chirality is :
  1. The product obtained by SN2 reaction of haloalkane having chirality at the reactive site shows inversion of configuration.
  2. Enantiomers are superimposable mirror images on each other.
  3. A racemic mixture shows zero optical rotation.
  4. SN1 reaction yields 1:1   mixture of both enantiomers.

Solution

The product obtained by SN2 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.
