Hydration of alkenes under aqueous acidic conditions. Draw the detailed stepwise mechanism for this reaction. Be sure to show all steps, intermediates, formal charges, and show the movement of electrons with curved arrows. You do not need to draw transition states. H2SO4 H20 ?? The hydration of alkynes can also occur under aqueous acidic conditions however, instead of forming the alcohol, a ketone is formed. Draw the detailed stepwise mechanism for the conversion of the alkyne to the ketone (one...

CECH HO, H,SO4 HgSO4 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 cnol immediately rearranges to a more stable ketone...
