प्रश्न
Halo alkanes react with alkalies to produce alcohol. Give the equation for the preparation of the second member of the homologous series of alcohol. State under what condition the reaction occurs.
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.
\[\ce{C2H5Cl + NaOH -> \underset{Ethyl alcohol}{C2H5OH} + NaCl}\]
\[\ce{C2H5Br + KOH -> KBr + \underset{Ethyl alcohol}{C2H5OH}}\]
