    \[{{C}_{4}}{{H}_{11}}N\] shows how many primary amines?

    A)  \[1\]                    

    B)         \[2\]

    C)  \[3\]                    

    D)         \[4\]

    Correct Answer: D

    Solution :

    \[{{C}_{4}}{{H}_{11}}N\]shows following 4 types of primary amines \[\underset{\text{n-butyl}\,\text{amine}}{\mathop{C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}N{{H}_{2}}}}\,\] \[\underset{\text{sec}\text{. butyl amine}}{\mathop{C{{H}_{3}}-C{{H}_{2}}-\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{C}}\,}}\,H-N{{H}_{2}}}}\,\] \[\underset{\text{Isobutyl amine}}{\mathop{C{{H}_{3}}-\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C}}\,}}\,H-C{{H}_{2}}-N{{H}_{2}}}}\,\] \[\underset{\text{t-butyl amine}}{\mathop{C{{H}_{3}}-\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-N{{H}_{2}}}}\,\]
