1. Draw the mechanism for this reaction **Figure 28: 7-hydroxy-4-methylcoumarin Synthesis from Resorcinol & Ethyl Acetoacetate**The image shows a chemical reaction for synthesizing 7-hydroxy-4-methylcoumarin. The reaction involves the following components:- **Reactants:** - Resorcinol (Chemical structure: a benzene ring with two hydroxyl groups at positions 1 and 3) - Ethyl acetoacetate (Chemical structure: a ketone group adjacent to an ester group)- **Conditions:** - **Amberlyst-15**: A catalyst used in the reaction - **Toluene**: Used as the solvent- **Product:** - 7-hydroxy-4-methylcoumarin (Chemical structure: a benzene ring fused with a pyrone ring, hydroxyl group at position 7)**Pre-Lab Questions:**- Draw the mechanism for this reaction.**Explanation:**This reaction is typically a Pechmann condensation, an organic reaction to synthesize coumarins. The page instructs students to draw the detailed mechanism, illustrating the electron movement and intermediate structures involved during the synthesis process.

In the given reaction, Amberlyst -15 is a strongly acidic cation exchange resin used as a heterogeneous acid catalysis. In non-aqueous medium catalysis occurs. The product formed is called coumarins which are important class of benzopyrones which contain fused both benzene ring and pyrone rings. They are used as additives in food, perfumes, agrochemicals, cosmetics, pharmaceuticals and in the manufacture of insecticides and fluorescent dye lasers. For the given reaction, the reactants are resorcinol and ethyl acetoacetate. The mechanism of the reaction is as shown below:
