Explain the acidic nature of phenols and compare with that of alcohol.

Phenols are more acidic than that of alcohols reason
$\underset{\mathrm{phenol}}{{\mathrm{C}}_6{\mathrm{H}}_5\mathrm{OH}}\rightleftharpoons \underset{\mathrm{phenoxide} \mathrm{ion}}{{\mathrm{C}}_6{\mathrm{H}}_5{\mathrm{O}}^{-}+{\mathrm{H}}^{+}}$
$\underset{\mathrm{alcohol}}{{\mathrm{C}}_2{\mathrm{H}}_5\mathrm{OH}}\rightleftharpoons \underset{\mathrm{alkoxide} \mathrm{ion}}{{\mathrm{C}}_2{\mathrm{H}}_5{\mathrm{O}}^{-}+{\mathrm{H}}^{+}}$
Phenoxide ion is stabilized by resonance more the stability of phenoxide ion, more will be the acidic nature of phenol.

But alkoxide ion is not stabilized by resonance. Hence alcohol is less acidic.
