    B) 1-Butyne

    C) 2-Butene

    D) All of these

    Correct Answer: C

    Solution :

    \[C{{H}_{3}}-\underset{\underset{H\,\,\,}{\mathop{|\,\,\,\,\,}}\,}{\mathop{CH}}\,-\underset{\underset{Cl\,\,}{\mathop{|\,\,\,\,}}\,}{\mathop{CH}}\,-\underset{\underset{H\,\,\,\,\,}{\mathop{|\,\,\,\,\,\,\,\,}}\,}{\mathop{C{{H}_{2}}}}\,\underset{-\,HCl}{\mathop{\xrightarrow{alc.\,NaOH}}}\,\]\[C{{H}_{3}}CH=CH-C{{H}_{3}}\]
