Vedclass · Answer

(C) Dehydrohalogenation of an alkyl halide is an elimination reaction.In this reaction,a hydrogen atom is removed from the $\beta$-carbon and a halogen atom is removed from the $\alpha$-carbon in the presence of an alcoholic base like $KOH$,resulting in the formation of an alkene.$CH_3CH_2Br + 	ext{alc. } KOH 	o CH_2 = CH_2 + KBr + H_2O$There are two main types of elimination reactions:$(i)$ $E_1$: Unimolecular elimination$(ii)$ $E_2$: Bimolecular elimination
