alleryPhenol is more acidic than ethanol because:
APhenol has a stronger O-H bond than ethanol always
BThe phenoxide ion is stabilised by aromatic resonance
CEthanol is fully covalent while phenol is ionic in nature
DPhenol is heavier so it dissociates more in water always
Answer & Solution
Correct answer: B. The phenoxide ion is stabilised by aromatic resonance
Phenoxide ion's negative charge is delocalised into the benzene ring, stabilising it
phenol's $pK_a \approx 10$, ethanol's $\approx 16$.
