    Using anhydrous\[AlC{{l}_{3}}\]as catalyst, which one of the reaction produces ethyl benzene?

    A) \[C{{H}_{3}}C{{H}_{2}}OH+{{C}_{6}}{{H}_{6}}\]

    B) \[C{{H}_{3}}CH=C{{H}_{2}}+{{C}_{6}}{{H}_{6}}\]

    C) \[C{{H}_{2}}=C{{H}_{2}}+{{C}_{6}}{{H}_{6}}\]

    D) \[C{{H}_{3}}-C{{H}_{3}}+{{C}_{6}}{{H}_{6}}\]

    Correct Answer: A

    Solution :

    (a, c) \[{{C}_{6}}{{H}_{5}}+C{{H}_{2}}=C{{H}_{2}}\xrightarrow[\Delta ,P]{AlC{{l}_{2}}}\] \[\underset{(See\,Friedel-Crafts\,reaction)}{\mathop{{{C}_{6}}{{H}_{5}}{{C}_{2}}{{H}_{5}}}}\,\]
