    A)                 \[PC{{l}_{5}}\]  

    B)                 \[NaOH+B{{r}_{2}}\]

    C)                 Sodalime            

    D)                 Hot conc. \[{{H}_{2}}S{{O}_{4}}\]

    Correct Answer: B

    Solution :

               \[\underset{\text{Acetamide}}{\mathop{C{{H}_{3}}CON{{H}_{2}}}}\,+B{{r}_{2}}+4NaOH\to \]\[\underset{\text{Methyl amine}}{\mathop{C{{H}_{3}}N{{H}_{2}}}}\,+N{{a}_{2}}C{{O}_{3}}+2NaBr+2{{H}_{2}}O\]
