The reaction shown in the image involves the following steps:
Step 1: The compound with a hydroxyl group attached to a benzene ring (phenol) reacts with NaOH and CO₂, leading to the formation of salicylate (compound A).
Step 2: The reaction of salicylate with acetylation (in the presence of (CH₃CO)₂O) results in the formation of aspirin (compound Y).
The major product Y in the reaction is aspirin.
Thus, the correct answer is Option D: Aspirin.
In the given reaction, the starting compound is a phenol group (-OH) attached to a benzene ring. The sequence of reactions involves:
1. Reaction with NaOH: This leads to the formation of the phenoxide ion (A).
2. Reaction with CO$_2$: This results in the formation of a carboxylated product, which is an intermediate that undergoes decarboxylation upon acidic work-up.
3. Formation of (B): The product of the reaction after the introduction of acetic anhydride (CH$_3$COO) under acidic conditions is aspirin (acetylsalicylic acid).
Thus, the final major product (Y) is aspirin, which is formed after the phenol is acetylated by acetic anhydride.
Hence, the correct answer is aspirin.
