    \[C{{H}_{3}}-C{{H}_{2}}-O-C{{H}_{2}}-C{{H}_{3}}\] reacts with hot and excess HI, then formed product is : \[C{{H}_{3}}-C{{H}_{2}}-I\]and\[C{{H}_{3}}C{{H}_{2}}OH\]

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

    B) \[C{{H}_{3}}-C{{H}_{3}}\]

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

    D)  none of the above

    Correct Answer: C

    Solution :

    When\[C{{H}_{3}}C{{H}_{2}}-O-C{{H}_{2}}-C{{H}_{3}}\]reacts with hot and excess\[HI\].two moles of ethyl iodide are formed. \[\underset{di\,\,ethyl\,\,ether}{\mathop{C{{H}_{3}}C{{H}_{2}}OC{{H}_{2}}C{{H}_{3}}}}\,+2HI\to \underset{ethyl\,\,iodide}{\mathop{2C{{H}_{3}}C{{H}_{2}}I}}\,+{{H}_{2}}O\]
