  • question_answer
    The number of structural isomers possible from the molecular formula \[{{C}_{3}}{{H}_{9}}N\] is                                             

    A)  4                            

    B)  5                            

    C)  2                            

    D)  3

    Correct Answer: A

    Solution :

    Structural isomers of \[{{C}_{3}}{{H}_{9}}N\] are \[\underbrace{C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}N{{H}_{2}},C{{H}_{3}}-\underset{\underset{N{{H}_{2}}}{\mathop{|}}\,}{\mathop{C}}\,H-C{{H}_{3}}}_{{{1}^{{}^\circ }}-\text{amine}}\] \[C{{H}_{3}}-C{{H}_{2}}-NH-C{{H}_{3}},C{{H}_{3}}-\underset{\underset{\underset{\,\,\,{{3}^{{}^\circ }}\text{amine}}{\mathop{C{{H}_{3}}}}\,}{\mathop{|}}\,}{\mathop{N}}\,-C{{H}_{3}}\]
