    Consider the following reaction, \[ethanol\xrightarrow{PB{{r}_{3}}}X\xrightarrow{alc.KOH}Y\xrightarrow[(ii)\,\,{{H}_{2}}O\,.\,\Delta ]{(i)\,{{H}_{2}}S{{O}_{4}}\,roomtemp.}Z;\]the product Z is

    A)  \[C{{H}_{2}}=C{{H}_{2}}\]              

    B)  \[C{{H}_{3}}C{{H}_{2}}-O-C{{H}_{2}}C{{H}_{3}}\]

    C)  \[C{{H}_{3}}C{{H}_{2}}OH\]

    D)  \[C{{H}_{3}}-C{{H}_{2}}-O-S{{O}_{3}}H\]

    Correct Answer: C

    Solution :

    \[{{C}_{2}}{{H}_{5}}OH\xrightarrow{PB{{r}_{3}}}{{C}_{2}}{{H}_{5}}Br\xrightarrow{Alc.\,KOH}C{{H}_{2}}=C{{H}_{2}}\] \[\xrightarrow{{{H}_{2}}S{{O}_{4}}}C{{H}_{3}}C{{H}_{2}}OS{{O}_{3}}H\] \[\xrightarrow[-{{H}_{2}}S{{O}_{4}}]{{}^{{{H}_{2}}O}/{}_{\Delta }}\underset{ethanol}{\mathop{C{{H}_{3}}C{{H}_{2}}OH}}\,\]
