    All carbon atoms are\[s{{p}^{2}}-\]hybridised in

    A)  1, 3-butadiene                

    B)  \[C{{H}_{2}}=C=C{{H}_{2}}\]

    C)  cyclohexane    

    D)         2-butene

    E)  \[CH\equiv CC\equiv CH\]

    Correct Answer: A

    Solution :

    \[\underset{1,3-butadiene}{\mathop{\overset{s{{p}^{2}}}{\mathop{C{{H}_{2}}}}\,=\overset{s{{p}^{2}}}{\mathop{CH}}\,-\overset{s{{p}^{2}}}{\mathop{CH}}\,=\overset{s{{p}^{2}}}{\mathop{C{{H}_{2}}}}\,}}\,\]
