Identify false statement regarding aspirin.
Options
- AIt contains amide linkage.
- BIt is obtained from salicylic acid.
- CIt has fewer side effects than salicylic acid.
- DIt has stomach irritating side effects.
Correct answer
A. It contains amide linkage.
Step-by-step solution
Aspirin (acetylsalicylic acid) contains an ester linkage ( -OCOCH ₃ ) rather than an amide group, making statement A incorrect. Statement B is valid as aspirin is synthesized through acetylation of salicylic acid using acetic anhydride. Statement C holds since aspirin was developed specifically to reduce the gastric irritation associated with salicylic acid. Statement D is correct due to aspirin's inhibition of cyclooxygenase enzymes, which leads to stomach irritation. The false statement is therefore A .
