In which of the following reactions alcohol is produced?
Correct answer: B. Reaction of alkyl halide with alcoholic KOH
- A. Reaction of alkyl halide with aqueous KOH
- B. Reaction of alkyl halide with alcoholic KOH
- C. Reaction of alkyl halide with KCN followed by acidic hydrolysis
- D. Reactions of alkyl halide with sodium alkoxide
Explanation
The correct option for the production of alcohol is B. In the reaction of alkyl halide with alcoholic KOH (option B), an elimination reaction (usually E2) occurs, resulting in the formation of an alkene and an alcohol.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
