c=CH H20, H2SO4 H9SO4 `CH3 Alkynes do not react directly with aqueous acid as do alkenes, but will do so in the presence of mercury(II) sulfate as a Lewis acid catalyst. The reaction occurs with Markovnikov regiochemistry, so the OH group adds to the more highly substituted carbon and the H adds to the less highly substituted carbon. The initial product of the reaction is a vinyl alcohol, also called an enol. The enol immediately rearranges to a more stable ketone via tautomerization. Draw curved arrows to show the movement of electrons in this step of mechanism. Arrow-pushing Instructions Hjö: H- -CH3 -CH3 H3O*

46. In order to determine the ident ity of an alkene, a chemist reacts it with water. She then separates the product of this reaction into two equal amounts in conta iner X and container Y. To container X, a strong oxidizing agent is added. The resulting product will react with a base to form a salt and water. When the new product in container X is mixed with conta iner Y and H2SO4 is added, the chemist is able to confirm that: H3C CH2-C-0-CH2-CH2-CH3 has been formed.
