Vedclass · Answer

(A) In the case of alkyl halides,the nature of the reagent determines whether substitution or elimination occurs.$1$. Nucleophilic substitution: When an alkyl halide is treated with an aqueous solution of a strong base like $KOH$ or $NaOH$,the $OH^-$ ion acts as a nucleophile and replaces the halogen atom,resulting in an alcohol.$2$. $\beta$-Elimination (Dehydrohalogenation): When an alkyl halide is treated with an alcoholic solution of a strong base like $KOH$,the $OH^-$ ion acts as a base and abstracts a proton from the $\beta$-carbon,leading to the formation of an alkene.

Elimination reactions (especially $\beta$-elimination) are as common as the nucleophilic substitution reaction in the case of alkyl halides. Specify the reagents used in both cases.
