    \[{{C}_{2}}{{H}_{5}}OH\xrightarrow[NaOH]{{{I}_{2}}}A\xrightarrow[KOH]{Aqueous}B\]In equation given above A and B are respectively

    A)  \[CH{{I}_{3}}\]and  \[HCOOK\]

    B)  \[CH{{I}_{3}}\] and \[C{{H}_{3}}COOK\]

    C)  \[C{{H}_{4}}\]and \[HCOOK\]

    D)  \[CH{{I}_{3}}\] and \[{{H}_{2}}\]

    Correct Answer: A

    Solution :

    \[{{C}_{2}}{{H}_{5}}OH+4{{I}_{2}}+6NaOH\xrightarrow{{}}\underset{Iodofrom}{\mathop{CH{{I}_{3}}}}\,\] \[+HCOONa+5NaI+5{{H}_{2}}O\]                 \[CH{{I}_{3}}+3KOH\xrightarrow{{}}\left[ H-\underset{OH}{\mathop{\underset{|}{\mathop{\overset{OH}{\mathop{\overset{|}{\mathop{C}}\,}}\,}}\,}}\,-OH \right]\xrightarrow{-{{H}_{2}}O}\]                                                 \[H-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-OH\]                 \[H-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-OH+KOH\xrightarrow{{}}H-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-OK+{{H}_{2}}O.\]
