  • question_answer
    The reaction of HBr with \[\overset{\overset{\,\,\,\,\,\,C{{H}_{3}}}{\mathop{|\,}}\,}{\mathop{C{{H}_{3}}-C=C{{H}_{2}}}}\,\] in the presence of peroxide will give [BHU 2005]

    A) \[\underset{\underset{C{{H}_{3}}}{\mathop{|\,\,\,\,\,\,\,}}\,}{\mathop{C{{H}_{3}}CBrC{{H}_{3}}}}\,\]

    B) CH3CH2CH2CH2Br

    C) \[\overset{\overset{C{{H}_{3}}}{\mathop{|\,\,\,\,\,\,\,\,\,\,\,}}\,}{\mathop{C{{H}_{3}}CHC{{H}_{2}}Br}}\,\]

    D) \[\overset{\overset{\,\,\,\,\,\,\,\,\,\,\,\,\,C{{H}_{3}}}{\mathop{\,\,\,\,\,\,\,\,\,\,|}}\,}{\mathop{C{{H}_{3}}C{{H}_{2}}CHC{{H}_{3}}}}\,\]

    Correct Answer: C

    Solution :

    \[\underset{\,\,\,\,C{{H}_{3}}}{\mathop{\underset{|}{\mathop{C{{H}_{3}}-C=C{{H}_{2}}}}\,}}\,\underset{anti.\,Markownkoffs\,addtion}{\mathop{\xrightarrow{\,\,\,HBr/peroxide\,\,\,\,\,\,}}}\,\underset{C{{H}_{3}}\,\,}{\mathop{\underset{|\,\,\,\,\,\,\,\,\,\,\,}{\mathop{C{{H}_{3}}-CHC{{H}_{2}}-Br}}\,}}\,\]
