Chemistry - Hydrocarbon Question with Solution | TestHub

Both$\mathrm{Z}\mathrm{n}\left(\mathrm{H}\mathrm{g}\right),\mathrm{}\mathrm{}\mathrm{H}\mathrm{C}\mathrm{l}$and$\mathrm{N}{\mathrm{H}}_2\mathrm{N}{\mathrm{H}}_2,\mathrm{}\mathrm{}\mathrm{O}{\mathrm{H}}^{-}$can reduce$-\mathrm{C}\mathrm{O}\mathrm{C}{\mathrm{H}}_3$group to$-\mathrm{C}{\mathrm{H}}_2-\mathrm{C}{\mathrm{H}}_3$group, but HCl will also bring about protonation of alcohol to form alkyl halide. Therefore, appropriate reagent for the conversion is$\mathrm{N}{\mathrm{H}}_2\mathrm{N}{\mathrm{H}}_2,\mathrm{}\mathrm{}\mathrm{O}{\mathrm{H}}^{-}$.
