Vedclass · Answer

(B) $Assertion$ is correct because $tert$-butyl bromide is a $3^\circ$ alkyl halide,which undergoes $E2$ elimination rather than $S_N2$ substitution when treated with a strong base like sodium methoxide. The major product is isobutylene $(CH_3-C(CH_3)=CH_2)$.$Reason$ is also correct because sodium methoxide $(CH_3ONa)$ is indeed a strong nucleophile,but its primary role in this specific reaction with a bulky $3^\circ$ substrate is that of a strong base.However,the reason for the failure of the reaction is the steric hindrance of the $3^\circ$ alkyl halide,not just the nucleophilicity of the methoxide ion. Thus,the Reason is not the correct explanation for the Assertion.

Assertion: $tert$-Butyl methyl ether is not prepared by the reaction of $tert$-butyl bromide with sodium methoxide.
Reason: Sodium methoxide is a strong nucleophile.
