What makes ethanoic acid a stronger acid than ethanol ?

Explanation

As ethanoate ion is resonance stabilised it pushes equilibrium in the forward direction making ethanoic acid a stronger acid.
`underset("Ethanol")(CH_(3)CH_(2)OH) rarr underset("Ethoxide ion")(CH_(3)CH_(2)-O^(-)) + H^(+)`
In ethoxide ion the electron releasing effect of ethyl group intensifies charge on oxygen thus making its less stable. It pushes the equilibrium in the backward direction making ethanol a very weak acid (weaker than even water).
