    \[Iso-\]propyl amine with excess of acetyl chloride will give

    A) \[{{(C{{H}_{3}}CO)}_{2}}N-C-{{(C{{H}_{3}})}_{3}}\]

    B) \[{{(C{{H}_{3}})}_{2}}CH-\underset{\begin{smallmatrix}  | \\  H \end{smallmatrix}}{\mathop{N}}\,-COC{{H}_{3}}\]

    C) \[{{(C{{H}_{3}})}_{2}}CHN{{(CO{{H}_{3}})}_{2}}\]

    D) \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}-\underset{\begin{smallmatrix}  | \\  H \end{smallmatrix}}{\mathop{N}}\,-COC{{H}_{3}}\]

    Correct Answer: C

    Solution :

    \[{{(C{{H}_{3}})}_{2}}CH\cdot N{{H}_{2}}+2C{{H}_{3}}COCl\xrightarrow[-HCl]{}\] \[iso.\text{propyl}\,\,\text{amine}\] \[(pri\,\,\text{amine)}\]                                 \[{{(C{{H}_{3}})}_{2}}CH-N{{(COC{{H}_{3}})}_{2}}\]
