  • question_answer
    Number of isomeric primary amines obtained from\[{{C}_{4}}{{H}_{11}}N\]are:

    A)  3                                            

    B)  4

    C)  5                                            

    D)  6

    Correct Answer: B

    Solution :

                     Four isomeric primary amines of\[{{C}_{4}}{{H}_{11}}N\]are possible. \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{2}}N{{H}_{2}}\] \[{{(C{{H}_{3}})}_{2}}CHC{{H}_{2}}N{{H}_{2}}\] \[C{{H}_{3}}-\underset{\begin{smallmatrix}  | \\  C{{H}_{3}} \end{smallmatrix}}{\overset{\begin{smallmatrix}  C{{H}_{3}} \\  | \end{smallmatrix}}{\mathop{C}}}\,-N{{H}_{2}}\] \[C{{H}_{3}}\overset{\begin{smallmatrix}  N{{H}_{2}} \\  | \end{smallmatrix}}{\mathop{C{{H}_{2}}}}\,CHC{{H}_{3}}\]
