How would you account for the following :
(i) Phenols are much acidic than alcohols.
(ii) The boiling points of ethers are much lower than those of alcohols of comparable molecular measses.

Text Solution

Verified by Experts

(i) It is because phenoxide ion is more stable than alkoxide ion, on account of resonance

(ii) It is because alcohols are associated due to intermolecular hydrogen bonding whereas ethers are not.
