Among alcohols and phenols which one is more acidic? and why? |
|
Answer» In phenol charge because of resonance this facilitates the heterolytic eleavage of OH bond resulting in the formation of phenoxide ion the benzene ring with draws the negative charge from oxygen atom hence phenutide ion formed is resonance stabilizes done to this phenols are acidic in nature. But in alcohols neither does oxygen of OH group acquire positive change nor is the alkoxide ion is resonance stabilized in addition to this oxygen in alcohols is attached to electron donating alkyl groups these electron donating groups decrease the stability of alkoxide ion hence alcohol are not acidic. |
