Question

Which among the following is a dihydric phenol?

• A. p-Cresol
• B. Phloroglucinol
• C. Catechol
• D. Pyrogallol

Hint:

Number of \(-\text{OH}\) groups determines mono-, di-, or trihydric phenols.

Answer 1

The Correct Option is C

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.
