Vedclass · Answer

(A) When alkyl halides are heated with strong bases in an alcoholic solvent,they undergo a $1,2$-elimination reaction (specifically a dehydrohalogenation reaction) to form alkenes.Alcoholic $KOH$ (Alc. $KOH$) is a standard reagent used for this purpose because the ethoxide or hydroxide ion acts as a strong base to abstract a proton from the $\beta$-carbon,leading to the elimination of $HX$.

Alkene can be prepared from alkyl halide by the following reagent: $R-CH_2-CH_2-X + \text{Base} o \text{Alkene} + \text{Base-H} + X^-$
