Question:

What is the mechanism for the Aldol condensation for this experiment starting with Benzaldehyde and acetone (in the presence of NAOH/H2O) ?

Aldol Condensation:

Base catalyzed aldol reaction sometimes gives the aldol and some times the elimination product. The choice is partly based on conditions-the more vigorous conditions tend to give the elimination product.

The mechanism of this reaction is explained below.

step-1

As benzaldehyde has no alpha-hydrogen atom. So, acetone forms the enolate ion.

NaOH takes...

A reaction that causes a carbon-carbon bond and a enol or enolate molecule to form and reacts with an aldehyde or ketone is called an aldol condensation. Learn more about aldol condensation reactions and how it occurs in three steps: getting rid of the alpha hydrogen, forming new carbon and carbonyl bonds, and converting carbonyl groups to COH.
