    The major product formed in the following reaction. \[C{{H}_{3}}CH(Cl)C{{H}_{2}}-C{{H}_{2}}OH\xrightarrow{Aq.\,KOH}\] is

    A)  \[C{{H}_{3}}CH=CH-C{{H}_{2}}OH\]

    B)  \[C{{H}_{2}}=CH-C{{H}_{2}}-C{{H}_{2}}OH\]

    C)  

    D)  \[C{{H}_{3}}-\underset{OH}{\mathop{\underset{|}{\mathop{CH}}\,}}\,-C{{H}_{2}}-C{{H}_{2}}OH\]

    Correct Answer: D

    Solution :

    It is an example of nucleophilic substitution reaction. \[R-OH\xrightarrow{{}}R-OH+KX\] So, \[C{{H}_{3}}CH(Cl)C{{H}_{2}}-C{{H}_{2}}OH\xrightarrow{Aq.\,KOH}\]                           \[C{{H}_{3}}-\underset{\alpha ,wdiol.}{\mathop{\underset{OH}{\mathop{\underset{|}{\mathop{CH}}\,}}\,}}\,-C{{H}_{2}}-C{{H}_{2}}OH\]
