$CH_3-CH(C_2H_5)-CH_2-Br$

Vedclass · Answer

(A) In the compound $CH_3-CH(C_2H_5)-CH_2-Br$,the chiral center is located at the second carbon atom $(C2)$.The nucleophilic substitution by the $OH^{-}$ ion occurs at the first carbon atom $(C1)$,where the $Br$ atom is attached.Since the bonds connected to the chiral center are not broken or modified during the reaction,the spatial arrangement (configuration) around the chiral center remains unchanged.This results in the retention of configuration.

Which of the following compounds will show retention in configuration on nucleophilic substitution by $OH^{-}$ ion?
