Homework Answers
In presence of base acidic alpha hydrogen of the carbonyl group is removed and the carbon nucleophile is formed. This carbon nucleophile gives nucleophilic substitution reaction with an ester group by addition elimination mechanism.
There are two types of an alpha hydrogen atom to carbonyl groups, thus two calisen condensation products are possible.
Reactions are given in the image below.
