$1-$Bromobutane

Vedclass · Answer

(A) The reactivity of alkyl halides towards $S_{N}2$ reaction depends on the steric hindrance around the electrophilic carbon atom. The order of reactivity is: $Primary > Secondary > Tertiary$. Among the given options: $A$. $1-$Bromobutane is a primary alkyl halide with the least steric hindrance. $B$. $1-$Bromo-$2$-methylbutane is a primary alkyl halide but has more steric hindrance due to the methyl group at the $C-2$ position. $C$. $1-$Bromo-$2,2$-dimethylpropane is a primary alkyl halide but is highly hindered due to the two methyl groups at the $C-2$ position (neopentyl halide). $D$. $1-$Bromo-$3$-methylbutane is a primary alkyl halide with steric hindrance further away from the reaction site compared to $B$ and $C$. Since $1-$Bromobutane has the least steric hindrance,it is the most reactive towards $S_{N}2$ reaction.
