Chloroacetic acid has more `K_(a)` value than acetic acid. Explain.

Explanation

(i) For answer, consult section 17.
(ii) In carboxylic acids, the extent of intermolecular hydrogen bonding is more than in alcohols. That is why , boiling points are higher. For example, b-p. of `CH_(3)COOH` is 391K. While that of `CH_(3)CH_(2)OH` is 371 K.
(iii) For answer, consult section 17.
