A) \[{{C}_{2}}{{H}_{4}}+HCl\]
B) \[{{C}_{3}}{{H}_{6}}+B{{r}_{2}}\]
C) \[{{C}_{3}}{{H}_{6}}+HBr\]
D) \[{{C}_{3}}{{H}_{8}}+C{{l}_{2}}\]
E) \[{{C}_{2}}{{H}_{4}}+{{I}_{2}}\]
Correct Answer: C
Solution :
According to Markownikoffs rule, the addition of a unsymmetrical reagent (HX) 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 contains lesser number of H-atom. Hence, it is best applicable to the reaction between \[{{C}_{3}}{{H}_{6}}\]and \[HBr\]. \[\underset{\begin{smallmatrix} unsymmetric \\ \,\,\,\,\,\,alkene \end{smallmatrix}}{\mathop{C{{H}_{3}}CH=C{{H}_{2}}+HBr}}\,\xrightarrow{{}}C{{H}_{3}}-\underset{Br}{\mathop{\underset{\mathbf{|}}{\mathop{CH}}\,}}\,-C{{H}_{3}}\]
