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

Concept: Acetylation is a chemical reaction in which an acetyl group (\(-COCH_3\)) is introduced into a compound. Salicylic acid undergoes acetylation to form a widely used analgesic drug.
Reaction: Salicylic acid reacts with acetic anhydride in presence of an acid catalyst (like conc. \(H_2SO_4\)). \[ \text{Salicylic acid} + (CH_3CO)_2O \rightarrow \text{Acetylsalicylic acid} + CH_3COOH \]
Product Formed: Acetylsalicylic acid is commonly known as Aspirin.
Explanation:
The phenolic \(-OH\) group of salicylic acid gets acetylated.
This reduces irritation and enhances medicinal properties.
Aspirin is used as a pain reliever, antipyretic, and anti-inflammatory drug.
\[ \boxed{\text{Answer: Aspirin}} \]
