    Which of the following compounds have more than one hybridization for carbon? I. \[C{{H}_{3}}C{{H}_{2}}C{{H}_{2}}C{{H}_{3}}\] II. \[C{{H}_{3}}-CH=CH-C{{H}_{3}}\] III. \[C{{H}_{2}}=CH-CH=C{{H}_{2}}\] IV. \[H-C\equiv C-H\]

    A)  II.                 

    B)  III and IV

    C)  I and IV          

    D)  II and III

    Correct Answer: A

    Solution :

     In\[\overset{s{{p}^{3}}}{\mathop{C{{H}_{3}}}}\,-\overset{s{{p}^{2}}}{\mathop{CH}}\,=\overset{s{{p}^{2}}}{\mathop{CH}}\,-\overset{s{{p}^{3}}}{\mathop{C{{H}_{3}}}}\,,\]two types of hybridisation (\[s{{p}^{2}}\]and\[s{{p}^{3}}\]) are present.
