Vedclass · Answer

(C) Racemisation occurs via an $S_N1$ mechanism,which involves the formation of a carbocation intermediate. The stability of the carbocation determines the rate and the extent of racemisation.Option $C$ features a central carbon attached to two phenyl rings,one of which has a methoxy $(-OCH_3)$ group at the para position. The methoxy group is a strong electron-donating group by resonance ($+M$ effect),which significantly stabilizes the resulting carbocation intermediate.Greater stability of the carbocation leads to a more planar and longer-lived intermediate,which allows the nucleophile $(H_2O)$ to attack from either side with equal probability,resulting in maximum racemisation.Therefore,the substrate in option $C$ will give maximum racemisation.

For the given reaction
$R_1-C(R)(X)-R_2 \xrightarrow{HOH} R_1-C(R)(OH)-R_2$
Which substrate will give maximum racemisation?
