difference in acidity of alcohols phenols and carboxylic acids
Why are alcohols weaker than carboxylic acids?
Alkoxide ions also lack the ability to delocalise the charge density on the entire ion The conjugate bases of alcohols are therefore less stable than the alcohols themselves and are more likely to reform the alcohol This means that alcohols are weaker acids compared to carboxylic acids and phenols
Why are carboxylic acids more acidic than phenols?
On the other hand in the case of phenols, negative charge is less effectively delocalized over one oxygen atom and less electronegative carbon atoms in phenoxide ion. Therefore, the carboxylate ion exhibits higher stability in comparison to phenoxide ion. Hence, carboxylic acids are more acidic than phenols.
