Explanation of Solution
The aldol product that is formed by the reaction of the two molecules of butanal in the presence of base is shown as,
Figure 1
In this reaction, first of all, one equivalent of butanal is treated with the strong base that results in the formation of a resonance-stabilized enolate ion. This enolate ion reacts with the second equivalent of butanal followed by the hydrolysis that leads to the formation of the desired product,
