JEE Main Chemistry question

Phenol is more acidic than alcohol because **[BCECE 2007, MHT-CET 2007]**

(A)Phenol is more soluble in polar solvents
(B)Alcohol does not lose hydrogen atom
(C)Phenoxide ion is stabilised by resonanceCorrect
(D)Phenoxide ion doesn't exhibit resonance

Answer: (C)

Solution

When phenol loses a proton, the resulting phenoxide ion is stabilised by resonance delocalisation of the negative charge into the aromatic ring, which lowers its energy and favours ionisation.
