Worked practice questions

**Order of acidity** of phenol, water, ethanol:

  1. Phenol > water > ethanol
  2. Ethanol > water > phenol
  3. Water > phenol > ethanol
  4. All equal
Show answer and solution

Correct answer: A. Phenol > water > ethanol

pKa values: phenol 10.0 water 15.7; ethanol 15.9. So acidity: phenol > water > ethanol. **Conjugate-base stability:** PhO⁻ (resonance) > OH⁻ > EtO⁻ (+I from ethyl destabilises).
