The following reaction will give one major alkene product via the E1 mechanism. In the boxes draw the mechanism arrows, and in the final box draw the major alkene product, Be sure to include all lone pairs of electrons and nonzero formal charges on all species.
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...
