Question

Identify the structure of paracetamol from the following.

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

Paracetamol has an -OH group and an acetamido group (-NHCOCH3) para to each other on a benzene ring.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept
Paracetamol is an analgesic and antipyretic. Its name is N-(4-hydroxyphenyl)ethanamide.

Step 2: Features of the structure
A benzene ring carries a hydroxyl group and an acetamido group, -NHCOCH3, at para positions.

Step 3: Choose the structure
Other structures in the list are a urea derivative, a carbamic acid derivative and a methylated analogue. Only the structure with just -OH and -NHCOCH3 para to each other is paracetamol.

Final Answer:
Paracetamol is the structure with -OH and -NHCOCH3 para on benzene. \[ \boxed{\text{(D) }\text{the structure of 4-hydroxyacetanilide (paracetamol)}} \]
