Which one of the following is not formed when acetone reacts with 2 -pentanone in the presence of dilute NaOH followed by heating?

Correct answer

0

Step-by-step solution

This reaction is an example of cross aldol condensation reaction. In this reaction mixture of products will be formed by two different reactants. Two diffrent alpha hydrogen are present in 2-pentanone and one alpha hydrogen is present in acetone. Hence, three cross aldol and three self aldol products are possible. Few products are shown below. .
