Question:
Which of the following is NOT phenol?
Which of the following is NOT phenol?
Show Hint
Phenol = Ar-OH. Aromatic Alcohol = Ar-Alkyl-OH.
Updated On: Apr 30, 2026
- Phenol ($C_6H_5OH$)
- o-Cresol
- Hydroquinone
- Benzyl alcohol
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Definition of Phenol
A phenol is a compound where the hydroxyl ($-OH$) group is directly attached to the aromatic benzene ring.
Step 2: Analysis
- (A), (B), and (C) all have $-OH$ groups directly bonded to the ring. - (D) Benzyl alcohol ($C_6H_5CH_2OH$) has the $-OH$ group attached to an $sp^3$ hybridized side-chain carbon.
Step 3: Conclusion
Benzyl alcohol is an aromatic alcohol, not a phenol.
Final Answer:(D)
