Why is phenol acidic and hexanol neutral towards solution of `NaOH` ?

Text Solution

Verified by Experts

In phenol, the phenate ion left after the release of `H^(+)` ion is resonance stabilised stabilised. Therefore, phenol is acidic in behaviour. However, no such resonance is possible in cyclohexanol and the release of `H^(+)` ion is difficult.
