Question

Acetylation of salicylic acid produces:

• A. Aspirin
• B. DDT
• C. Phenol
• D. BHC

Hint:

Aspirin is acetylsalicylic acid — formed by acetylation of the phenolic OH group of salicylic acid.

Answer 1

The Correct Option is A

To answer the question "Acetylation of salicylic acid produces:", we need to understand the chemical reaction involved.

Acetylation is a chemical process where an acetyl group is introduced into a compound. When salicylic acid undergoes acetylation, it reacts with acetic anhydride to produce aspirin (acetylsalicylic acid) and acetic acid.

The reaction can be represented as:

\(\text{C}_7\text{H}_6\text{O}_3 + \text{(CH}_3\text{CO)}_2\text{O} \rightarrow \text{C}_9\text{H}_8\text{O}_4 + \text{CH}_3\text{COOH}\)

Where:

• \(\text{C}_7\text{H}_6\text{O}_3\) is salicylic acid.
• \(\text{(CH}_3\text{CO)}_2\text{O}\) is acetic anhydride.
• \(\text{C}_9\text{H}_8\text{O}_4\) is aspirin.
• \(\text{CH}_3\text{COOH}\) is acetic acid.

Therefore, the acetylation of salicylic acid leads to the formation of aspirin.

Hence, the correct answer is "Aspirin".
