Question

Ibuprofen belongs to which chemical class?

• A. Salicylates
• B. Aryl propionic acid derivatives
• C. Indole acetic acids
• D. Fenamate derivatives

Hint:

Ibuprofen, naproxen, and ketoprofen are examples of aryl propionic acid derivative NSAIDs.

Answer 1

The Correct Option is B

Concept:
Ibuprofen is a non-steroidal anti-inflammatory drug, commonly called an NSAID. NSAIDs are classified chemically into different groups.

Step 1: Understanding ibuprofen.
Ibuprofen is used as an analgesic, antipyretic, and anti-inflammatory drug.

Step 2: Chemical class.
Ibuprofen contains an aryl group and propionic acid moiety. Therefore, it belongs to the aryl propionic acid derivative class.

Step 3: Examples of same class.
Other aryl propionic acid derivatives include:
• Naproxen
• Ketoprofen
• Flurbiprofen

Step 4: Checking other options.
Aspirin belongs to salicylates.
Indomethacin belongs to indole acetic acid derivatives.
Mefenamic acid belongs to fenamate derivatives.
Ibuprofen belongs to aryl propionic acid derivatives.

Step 5: Final answer.
Therefore, ibuprofen belongs to aryl propionic acid derivatives. \[ \boxed{\text{Aryl propionic acid derivatives}} \]
