Explanation:

Claisen condensation is a reaction between two molecules containing an ester functional group. Similar to ketones and aldehydes, esters are weakly acidic because the alpha hydrogen to the carbonyl group can be deprotonated in the presence of a base. The ion that is formed nucleophilicly bonds to a second ester molecule. As seen below, an ethoxide molecule expels. Additon of an acid in the final step gives the final product.
