Question:
Aspirin is synthesised from:
Aspirin is synthesised from:
Show Hint
Aspirin = Acetyl + Salicylic Acid. You need an acetylating agent like Acetic Anhydride.
Updated On: May 5, 2026
- Salicylic acid + Acetic anhydride
- Phenol + $HNO_{3}$
- Benzene + $Cl_{2}$
- Toluene + $KMnO_{4}$
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Aspirin (acetylsalicylic acid) is produced through an acetylation reaction, which is an esterification process.
Step 2: Meaning
The hydroxyl group ($-OH$) of salicylic acid is replaced by an acetyl group ($-COCH_{3}$).
Step 3: Analysis
When salicylic acid reacts with acetic anhydride in the presence of an acid catalyst, the acetyl group from the anhydride attaches to the oxygen of the salicylic acid.
Step 4: Conclusion
The reaction between salicylic acid and acetic anhydride yields aspirin and acetic acid as a byproduct. Final Answer: (A)
