Question

Among the following, which is more acidic?

• A. \( H_2O \)
• B. \( C_6H_5OH \)
• C. \( C_2H_5OH \)
• D. \( CH_3OCH_3 \)

Hint:

The acidity of organic compounds can be compared by evaluating the stability of their conjugate bases.

Answer 1

The Correct Option is B

Step 1: Acidity is determined by the stability of the conjugate base formed after losing a proton. Phenol (\( C_6H_5OH \)) is more acidic than water and ethanol due to resonance stabilization of its conjugate base (\( C_6H_5O^- \)). Ether (\( CH_3OCH_3 \)) does not release protons easily and is least acidic.
