The carboxylic acid is stronger than:
Correct answer: E. СН3ОН
- A. PCl3
- B. H2SO4
- C. HNO3
- D. HCI
- E. СН3ОН
Explanation
Methanol is a very weak acid with a much higher pKa (around 15.5) compared to carboxylic acids (pKa around 4-5). Carboxylic acids, like acetic acid, are much stronger due to their ability to stabilize the negative charge on the conjugate base (carboxylate anion) through resonance.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
