Write the structure of the aldol addition product of

(a)

(b)

(c)

Sample Solution (a) A good way to correctly identify the aldol addition product of any aldehyde is to work through the process mechanistically. Remember that the first step is enolate formation and that this must involve proton abstraction from the α carbon.

Now use the negatively charged α carbon of the enolate to form a new carbon-carbon bond to the carbonyl group. Proton transfer from the solvent completes the process.
