Vedclass · Answer

(C) The given reaction is a dehydrohalogenation reaction where a vicinal or geminal dihalide is converted into an alkyne. To convert a geminal dihalide $(R-CH_2-CCl_2-R)$ into an alkyne $(R-C \equiv C-R)$,a strong base is required to remove two molecules of $HCl$. $NaNH_2$ (sodamide) in liquid ammonia $(liq. NH_3)$ is a very strong base commonly used for this purpose. Therefore,the correct reagent is $NaNH_2$ in $liq. NH_3$.

The reagent for the reaction $R-CH_2-CCl_2-R \xrightarrow{\text{reagent}} R-C \equiv C-R$ is:
