Question:
Identify the structural formula of phloroglucinol.
Identify the structural formula of phloroglucinol.
Show Hint
Phloroglucinol is perfectly symmetrical. Think of a benzene ring where you skip one carbon between every -OH group.
Updated On: May 14, 2026
- Benzene ring with -OH groups at 1, 3, 5 positions
- Benzene ring with -OH groups at 1, 2, 3 positions
- Benzene ring with -OH groups at 1, 2, 4 positions
- Benzene ring with -OH groups at 1, 3 positions
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Concept
Phloroglucinol is a benzenetriol, which is an aromatic organic compound with three hydroxyl groups.
Step 2: Meaning
The relative positions of the hydroxyl groups define the specific trihydroxybenzene isomer.
Step 3: Analysis
- 1,2,3-trihydroxybenzene is Pyrogallol. - 1,2,4-trihydroxybenzene is Hydroxyquinol. - 1,3,5-trihydroxybenzene is Phloroglucinol.
Step 4: Conclusion
Phloroglucinol corresponds to the symmetrical 1, 3, 5-substitution. Final Answer: (A)
