    The Markownikoff?s rule is the best applicable to the reaction between:

    A)  \[{{C}_{2}}{{H}_{4}}+HCl\]                  

    B)  \[{{C}_{3}}{{H}_{6}}+B{{r}_{2}}\]

    C)  \[{{C}_{3}}{{H}_{6}}+HBr\]                  

    D)  \[{{C}_{3}}{{H}_{8}}+C{{l}_{2}}\]

    Correct Answer: C

    Solution :

    According to Markownikoff?s rule, the addition of a unsymmetrical reagent to an unsymmetric alkene takes place in such a way that the negative part of the reagent will be attached to the carbon atom which containing lesser number of H-atom. Hence it is best applicable to the reaction between \[{{C}_{3}}{{H}_{6}}\] and \[HBr\] \[C{{H}_{3}}CH=C{{H}_{2}}+HBr\xrightarrow{{}}C{{H}_{3}}-\underset{Br}{\mathop{\underset{|}{\mathop{C}}\,}}\,H-C{{H}_{3}}\]
