उत्तर
When ethyl halides are boiled with aqueous sodium hydroxide or potassium hydroxide, hydrolysis takes place with the formation of ethyl alcohol.
Condition: Alkyl halide is boiled with aqueous alkali.
\[\ce{C2H5Cl + NaOH -> \underset{Ethyl alcohol}{C2H5OH} + NaCl}\]
\[\ce{C2H5Br + KOH -> KBr + \underset{Ethyl alcohol}{C2H5OH}}\]
