Question:
Which among the following is a dihydric phenol?
Which among the following is a dihydric phenol?
Show Hint
Number of \(-\text{OH}\) groups determines mono-, di-, or trihydric phenols.
Updated On: Mar 28, 2026
- p-Cresol
- Phloroglucinol
- Catechol
- Pyrogallol
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Define dihydric phenol.
A dihydric phenol contains two hydroxyl (\(-\text{OH}\)) groups attached to a benzene ring.
Step 2: Analyze each option.
p-Cresol has one \(-\text{OH}\) group. Phloroglucinol and pyrogallol contain three \(-\text{OH}\) groups.
Step 3: Identify correct compound.
Catechol contains two hydroxyl groups in the ortho position.
Step 4: Conclusion.
Therefore, catechol is a dihydric phenol.
A dihydric phenol contains two hydroxyl (\(-\text{OH}\)) groups attached to a benzene ring.
