Solution
The conversion of an alkyl halide into an alkene by alcoholic KOH is classified as a dehydrohalogenation reaction.
Explanation:
When an alkyl halide is treated with an alcoholic solution of potassium hydroxide (KOH), hydrogen halide is removed. It leads to the production of alkene. This is an example of a dehydrohalogenation (β-elimination) reaction.
