  • question_answer The product obtained by treating: \[C{{H}_{3}}-CH=C{{H}_{2}}+HBr\to \]

    A) \[C{{H}_{3}}-CH=C{{H}_{2}}Br\]

    B) \[C{{H}_{2}}BrC{{H}_{2}}=C{{H}_{2}}\]

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

    D) \[C{{H}_{3}}-\underset{Br}{\mathop{\underset{|}{\mathop{CH}}\,}}\,-C{{H}_{3}}\]  

    Correct Answer: D

    Solution :

    \[C{{H}_{3}}CH=C{{H}_{2}}+HBr\xrightarrow{{}}C{{H}_{3}}-\underset{Br}{\mathop{\underset{|}{\mathop{C}}\,}}\,H-C{{H}_{3}}\] This is according to Markovnikov's rule. Hence, the correct option is [d].
