Question

Arrange the following compounds in the increasing order of acidity

Phenol.,, alcohol...,,water

Answer 1

2Phenol>water>ethanol
•phenol is more acidic than water because it has a tendency to lose H+ ion and form phenoxide ion and if water loses H+ ion it forms hydroxide which is not stabilized by
resonance.
•water having pH more than alcohol is more acidic than ethanol.

Here phenol is most acidic and ethanol is least acid

Answer 2

Phenol > water >alcohol
