Question:
Identify false statement regarding aspirin.
Identify false statement regarding aspirin.
Show Hint
Aspirin is acetylsalicylic acid, so its functional groups are ester and carboxylic acid, not amide.
Updated On: Nov 13, 2026
- It contains amide linkage.
- It is obtained from salicylic acid.
- It has fewer side effects than salicylic acid.
- It has stomach irritating side effects.
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept
Aspirin is the acetyl derivative of salicylic acid, made by acetylating the phenolic \(-\text{OH}\) group.
Step 2: Check each statement
It contains an ester group (\(-\text{OCOCH}_3\)) and a \(-\text{COOH}\) group, but no amide linkage, so option A is false.
It is obtained from salicylic acid, so B is true.
Step 3: Side effects
Aspirin is less irritating than salicylic acid, so C is true, but it can still irritate the stomach, so D is true.
Final Answer:
The false statement is that aspirin contains an amide linkage. \[ \boxed{\text{(A) }\text{It contains amide linkage.}} \]
