    What are the products in the following reaction? \[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}\xrightarrow[cold]{HI}X+Y\]

    A) \[C{{H}_{3}}COOH,C{{H}_{2}}=C{{H}_{2}}\]

    B) \[C{{H}_{3}}CHO,\,C{{H}_{2}}=C{{H}_{2}}\]

    C) \[{{C}_{2}}{{H}_{5}}OH,{{C}_{2}}{{H}_{5}}I\]

    D) None of the above

    Correct Answer: C

    Solution :

    Key Idea: When HI is present in less quantity and temperature is low, then two alkyl group separate and form one molecule of alcohol and other form alkyl halide. \[{{C}_{2}}{{H}_{5}}O{{C}_{2}}{{H}_{5}}+HI\xrightarrow{cold}\underset{\text{ethyl}\,\text{iodide}}{\mathop{{{C}_{2}}{{H}_{5}}I}}\,\]                                                                 \[+\,\underset{\text{ethyl}\,\text{alcohol}}{\mathop{\,{{C}_{2}}{{H}_{5}}OH}}\,\]
