    In which of the following reactions hydrogen gas will not be evolved?

    A) \[C{{H}_{3}}-C{{H}_{2}}-OH\xrightarrow{Na}\]

    B) \[C{{H}_{3}}-C{{H}_{2}}-OH\xrightarrow{K}\]

    C) \[C{{H}_{3}}-\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{C}}\,}}\,H-OH\xrightarrow{Al}\]

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

    Correct Answer: D

    Solution :

    [d] \[C{{H}_{3}}-\underset{C{{H}_{3}}}{\mathop{\underset{|}{\mathop{C}}\,}}\,H-\overset{-}{\mathop{O}}\,-\overset{+}{\mathop{H}}\,\xrightarrow{\overset{-}{\mathop{C}}\,{{H}_{3}}\overset{+}{\mathop{M}}\,gBr}C{{H}_{4}}\](Major product) Acid-base reaction takes place.
