The correct statement regarding nucleophilic substitution reaction in a chiral alkyl halide is:
The correct statement regarding nucleophilic substitution reaction in a chiral alkyl halide is:
Updated On: Mar 21, 2025
- Retention occurs in \(SN_1\) reaction and inversion occurs in \( SN_2 \) reaction.
- Racemisation occurs in \( SN_1 \) reaction and retention occurs in \( SN_2 \) reaction.
- Racemisation occurs in both \( SN_1 \) and \( SN_2 \) reactions.
- Racemisation occurs in \( S_N1 \) reaction and inversion occurs in \( S_N2 \) reaction.

The Correct Option is D
Solution and Explanation
- SN1 Reaction: This reaction proceeds via a carbocation intermediate, leading to a racemic mixture if the carbon is chiral, due to the planar nature of the carbocation.
- SN2 Reaction: This reaction involves a backside attack, resulting in inversion of configuration (Walden inversion) if the carbon is chiral.
Thus, racemisation occurs in SN1 reactions and inversion occurs in SN2 reactions.
