							Dear student

Phenol is a very weak acid and the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring.

Dear student 
Because in aqueous solution, when phenol releases H+ion then phenoxide ring is formed which is stabilised by resonance, so it can easily donate proton and show acidic behaviour. But in case of ethanol there is no kind of resonating structures are formed. so it doesn't show any acidic behaviour in aqueous solution.
