    D)  quaternary ammonium salt

    Correct Answer: D

    Solution :

     \[{{C}_{3}}{{H}_{9}}N\]represents \[\underset{1{}^\circ amine}{\mathop{C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}N{{H}_{2}}}}\,\leftarrow \to \underset{2{}^\circ a\min e}{\mathop{C{{H}_{3}}-\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C{{H}_{2}}}}\,-NH}}\,\] \[\underset{3{}^\circ amine}{\mathop{C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{N}}}\,}}\,\] It does not represent quaternary ammonium salt.
