Identify A and B in the following reaction

{\mathrm{C}_2}{\mathrm{H}_5}\mathrm{Cl\;}\xrightarrow{\mathrm{A}}\mathrm{\;}{\mathrm{C}_2}{\mathrm{H}_5}\mathrm{OH\;}\xleftarrow{\mathrm{B}}\mathrm{\;}{\mathrm{C}_2}{\mathrm{H}_5}\mathrm{Cl}

View answer and explanation

Correct option: A

A= aqueous KOH; B= AgOH

Option A (A= aqueous KOH; B= AgOH) is correct because aqueous KOH leads to substitution and AgOH, being a source of OH-, also leads to substitution.
