Q. Phenol is more acidic than alcohol because

Bihar CECEBihar CECE 2007Alcohols Phenols and Ethers

Solution:

Here is resonance. Due to resonance the phenoxide ion is more stable whereas resonance is not possible in alkoxide ion.

$R- O ^{\ominus}$ no resonance is possible,
Since, phenoxide ion is better stabilised by resonance, the phenol has more tendency to form phenoxide ion by releasing $H ^{+}$ion. So, phenols are acidic in nature.
