    A cetamide and ethylamine can be distinguished by reacting with

    A)  aqueous HCI and heat                 

    B)  aqueous NaOH and heat

    C)  acidified\[KMn{{O}_{4}}\]

    D)  bromine water

    Correct Answer: B

    Solution :

     \[C{{H}_{3}}CON{{H}_{2}}+NaOH\xrightarrow{\Delta }C{{H}_{3}}COONa+N{{H}_{3}}\]\[C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}+NaOH\xrightarrow{{}}\] No reaction\[N{{H}_{3}}\] will be liberated in acetamide which will give white fumes on treating with HCl whereas no such gas will be liberated in ethylamine.
