Which of the following is correct IUPAC name of catechol?
Show Hint
Ortho = 1,2 (Catechol); Meta = 1,3 (Resorcinol); Para = 1,4 (Quinol).
Updated On: Apr 26, 2026
- Benzene-1,2-diol
- Benzene-1,3-diol
- Benzene-1,4-diol
- Benzene-1,3,5-triol
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Identification
Catechol is a dihydroxybenzene where the two hydroxyl ($-OH$) groups are at the ortho positions relative to each other.
Step 2: IUPAC Nomenclature
Numbering the benzene ring to give the substituents the lowest possible locants, the positions are 1 and 2.
Step 3: Conclusion
The IUPAC name is Benzene-1,2-diol.
Final Answer: (A)
