Question

The IUPAC name of acetylsalicylic acid is

• A. 2-acetoxy benzoic acid
• B. 1-acetoxy benzoic acid
• C. 4-acetoxy benzoic acid
• D. 3-acetoxy benzoic acid

Hint:

In the IUPAC naming of acetylsalicylic acid, the acetyl group is attached to the second position of the benzene ring, hence the name "2-acetoxy benzoic acid".

Answer 1

The Correct Option is A

Step 1: Understand the structure of acetylsalicylic acid.
Acetylsalicylic acid, commonly known as aspirin, consists of a salicylic acid molecule where the hydroxyl group (-OH) is esterified with an acetyl group (-COCH\(_3\)) at the 2-position of the benzene ring.
Step 2: Apply the IUPAC naming convention.
According to IUPAC nomenclature, the hydroxyl group on the benzene ring is located at position 1, and the acetyl group is located at position 2 on the ring.
Hence, the correct IUPAC name is "2-acetoxy benzoic acid".
