Which one of the following is more acidic:
Correct answer: C. Carboxylic acid
- A. Phenol
- B. Alcohols
- C. Carboxylic acid
- D. Amines
Explanation
The lone pair of electron at O is greatly pulled by 2 electronegative atoms C and O so the electron density at the other O decreases and OH bond weakens and hence it gets easier to lose proton, this is why it is more acidic. Phenols are acidic as well , but less acidic than Carboxylic acid.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
