Answer 2

Answer:

Explanation:

Although there are 4 hydrogen in the structure, but CH​3 protons do not contribute to the acidity. ... There is no relation between the number of hydrogens and acidity. It is COOH hydrogen which makes it acidic. Acetic acid is a weak acid, since it does not dissociate completely in water to its constituent ions
