Question

Phenol is more acidic than cyclohexanol because:
  1. A
    Phenoxide is stabilised by resonance with the ring
    Correct
  2. B
    OH is more electronegative in phenol
  3. C
    Phenol has lower boiling point
  4. D
    Cyclohexanol is a stronger base

Correct answer

Phenoxide is stabilised by resonance with the ring

Explanation

Phenoxide ion (C₆H₅O⁻) is resonance-stabilised: the negative charge delocalises over the ring through 4 resonance structures. Cyclohexoxide has no such delocalisation. Greater anion stability → higher acidity of phenol.
