    Stability of\[iso-\]butylene can be best explained by

    A)  inductive effect

    B)  mesomeric effect

    C)  hyperconjugative effect

    D)  steric effect

    Correct Answer: C

    Solution :

     The structure of \[iso-\]butylene is \[{{H}_{3}}C-\overset{C{{H}_{3}}}{\mathop{\overset{|}{\mathop{C}}\,}}\,=C{{H}_{2}}\] Since, it has\[6\sigma ,\pi \]hyperconjugative structures, its stability is due to hyperconjugation.
