    B)                 Acetamide

    C)                 Acetone              

    D)                 Acetyl iodide

    Correct Answer: A

    Solution :

                    \[\underset{\text{Acetyl bromide}}{\mathop{C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-Br}}\,\underset{\text{(ii) Saturated }N{{H}_{4}}Cl}{\mathop{\xrightarrow{\text{(i) Excess-}C{{H}_{3}}MgI}}}\,\underset{\text{2-methyl 2-propanol}}{\mathop{C{{H}_{3}}-\underset{C{{H}_{3}}\ \ \ }{\overset{C{{H}_{3}}\ \ \ }{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,-OH}}}\,}}\,\]
