Updated On: Nov 12, 2026
- Benzene-1,3-diol
- 4-Methylphenol
- 4-Hydroxybenzaldehyde
- Benzene-1,2-diol
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept
Catechol is the common name of the ortho dihydroxybenzene.
Step 2: Positions
The two hydroxyl groups are on adjacent carbons, positions 1 and 2.
Step 3: Name
The IUPAC name is benzene-1,2-diol.
Final Answer:
The IUPAC name of catechol is benzene-1,2-diol. \[ \boxed{\text{(D) }\text{Benzene-1,2-diol}} \]
