Question:
Which of the following is NOT dihydric phenol?
Which of the following is NOT dihydric phenol?
Show Hint
"Di" means 2, "Tri" means 3; Phloroglucinol has 3 $-OH$ groups.
Updated On: May 14, 2026
- Catechol
- Phloroglucinol
- Resorcinol
- Hydroquinone
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept Dihydric phenols contain two hydroxyl ($-OH$) groups attached to the benzene ring.
Step 2: Meaning Catechol ($1,2$), Resorcinol ($1,3$), and Hydroquinone ($1,4$) are all benzenediols.
Step 3: Analysis Phloroglucinol is $1,3,5$-benzenetriol. It contains three hydroxyl groups.
Step 4: Conclusion Phloroglucinol is a trihydric phenol, not dihydric. Final Answer: (B)
