JEE Main 2024 — 27 January, Shift 1 — Question 71

The correct statement regarding nucleophilic substitution reaction in a chiral alkyl halide is ;

Option A:
Retention occurs in $\mathrm{S}_{\mathrm{N}} \mathrm{l}$ reaction and inversion occurs in $\mathrm{S}_{\mathrm{N}} 2$ reaction
Option B:
Racemisation occurs in $\mathrm{S}_{\mathrm{N}} \mathrm{l}$ reaction and retention occurs in $\mathrm{S}_{\mathrm{N}} 2$ reaction
Option C:
Racemisation occurs in both $\mathrm{S}_{\mathrm{N}} 1$ and $\mathrm{S}_{\mathrm{N}} 2$ reactions.
Option D:
Racemisation occurs in $\mathrm{S}_{\mathrm{N}} 1$ reaction and inversion occurs in $\mathrm{S}_{\mathrm{N}} 2$ reaction.
Correct

Answer: D

$\quad \mathrm{SN}^{1}-$ Racemisation

$\mathrm{SN}^{2}-$ Inversion
