Solution
Correct Answer:
Phenol>Water>Ethanol
Phenol is more acidic than water and ethanol because the phenoxide ion is resonance-stabilized. Water is more acidic than ethanol because the +I effect of the ethyl group in ethanol destabilizes the ethoxide ion. Therefore the correct order is phenol > water > ethanol.
This medium difficulty chemistry question is from the chapter organic compounds containing oxygen, covering the topic of phenols. It appeared in the 2025 exam.
