The chlorine atom has the positive inductive effect I+. It pulls the electron density away from the carboxylic group, thus enhancing its acidity. The effect is larger when the chlorine atom is located closer to the carboxylic group. Hence the 2-chloropropionic acid will have the significantly higher acidity compared with the 3-chloropropionic acid.
can you elaborate in terms of +I effect?
