How many aldol condensation products can be obtained when two aldehydes, both with \(\alpha \)-hydrogen atoms undergo reaction?

4

The correct answer is option 3. 4.

When two aldehydes, both with α-hydrogen atoms, undergo aldol condensation, they can form four possible products.

The aldol condensation reaction involves the nucleophilic addition of an enolate ion formed from one aldehyde to the carbonyl group of the other aldehyde, followed by dehydration to form the aldol product.

Let's denote the aldehydes as \(RCHO\) and \(R'CHO\). The possible aldol condensation products are:
