    Identify (C) in the following reaction series   \[\begin{align}   & Ethanol\xrightarrow{PB{{r}_{3}}}A\xrightarrow{Alc.KOH}B\xrightarrow[{{H}_{2}}O.heat]{{{H}_{2}}S{{O}_{4}},room\,\,\,\,temperataure}C \\  &  \\ \end{align}\]

    A) \[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}\]                

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

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

    D) \[C{{H}_{3}}C{{H}_{2}}OH\]

    Correct Answer: D

    Solution :

    \[\begin{align}   & {{C}_{2}}{{H}_{5}}OH\xrightarrow{PB{{r}_{3}}}\underset{(A)}{\mathop{{{C}_{2}}{{H}_{5}}Br}}\,\xrightarrow{Alc.\,KOH}\underset{(B)}{\mathop{C{{H}_{2}}=C{{H}_{2}}}}\, \\  & \mathop{\downarrow }_{{{H}_{2}}O/{{H}_{2}}S{{o}_{4}}} \\  & \underset{(C)}{\mathop{C{{H}_{3}}C{{H}_{2}}OC}}\, \\ \end{align}\]
