Vedclass · Answer

(C) The given reaction is a dehydrohalogenation reaction where two molecules of $HCl$ are removed from a gem-dihalide to form an alkyne.$R-CH_2-CCl_2-R$ undergoes elimination in the presence of a strong base like alcoholic $KOH$ or $NaNH_2$.However,for the conversion of a gem-dihalide to an alkyne,alcoholic $KOH$ is the standard reagent used to facilitate double dehydrohalogenation.Thus,the correct reagent is $KOH$ in $C_2H_5OH$.

The reagent used in the reaction $R-CH_2-CCl_2-R \xrightarrow{\text{Reagent}} R-C \equiv C-R$ is .............
