    The structure of isobutyl group in an organic compound is

    A)  

    B)  \[C{{H}_{3}}-\underset{|}{\mathop{CH}}\,-C{{H}_{2}}-C{{H}_{3}}\]

    C) \[C{{H}_{3}}-C{{H}_{2}}-C{{H}_{2}}-C{{H}_{2}}-\]

    D)  \[C{{H}_{3}}-\underset{C{{H}_{3}}}{\overset{C{{H}_{3}}}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-\]

    Correct Answer: A

    Solution :

     Iso mean one Me group is present in six chain. Hence, the structure of iso-butyl group in an organic compound is \[C{{H}_{3}}-\underset{H}{\overset{C{{H}_{3}}}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-C{{H}_{2}}-\]  (yl suffix is used to represent one -H less than the parent hydrocarbon.)
