Question

Arrange water, ethanol and phenol in increasing order of acidity and give reason for your answer

Answer 1

Phenol>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 acidic

Answer 2

Hey dear,

● Answer -
Increasing order of acidity is -
Ethanol < Water < Phenol

● Explaination -
- Water is neutral compound.
- Methyl is electron donating group, thus acidity is decreased.
- Phenyl group is electron withdrawing group, thus acidity is increased.
- Therefore, increasing order of acidity for given compounds is -
Ethanol < Water < Phenol

Hope this helped you.
