1. Hydration of acetaldehyde under acidic condition is shown in the figure below. The first step is protonation of the carbonyl oxygen with H+ of acid to generate a more electrophilic carbon. The water then attacks nucleophilically onto the electrophilic carbonyl carbon. Loss of an H+ to compensate the +ve charge developed on oxygen gives us the product.
2. Hydration of acetaldehyde under basic condition is shown below. The first step is attack of OH- onto the carbonyl carbon to generate a -vely charged Oxygen. The oxygen then picks up a proon from H2O in the system to yield the product as shon below.

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...
