WebThe chemical reaction occurs in the presence of alcoholic potassium hydroxide. The chemical reaction is represented as follows: C 2 H 5 Br g + KOH s → C 2 H 4 g + KBr s + H 2 O l. The reaction mechanism is given as-. The reaction where hydrogen halide is removed from the substrate is called dehydrohalogenation. Suggest Corrections. Traditionally, alkyl halides are substrates for dehydrohalogenations. The alkyl halide must be able to form an alkene, thus halides having no C–H bond on an adjacent carbon are not suitable substrates. Aryl halides are also unsuitable. Upon treatment with strong base, chlorobenzene dehydrohalogenates to give phenol via a benzyne intermediate. When treated with a strong base many alkyl chlorides convert to corresponding alkene. It is als…
