Chloroacetic acid

Vedclass · Answer

(B) The acidity of carboxylic acids depends on the stability of the conjugate base (carboxylate ion). Electron-withdrawing groups $(EWG)$ stabilize the carboxylate ion through the inductive effect ($-I$ effect),thereby increasing acidity.$1$. $CH_3CH_2COOH$ (Propionic acid): Contains an electron-donating alkyl group ($+I$ effect),which decreases acidity.$2$. $CH_3COOH$ (Acetic acid): Contains a methyl group ($+I$ effect),which is less electron-donating than the ethyl group in propionic acid.$3$. $HCOOH$ (Formic acid): No alkyl group attached to the carboxyl group.$4$. $ClCH_2COOH$ (Chloroacetic acid): Contains a chlorine atom,which is a strong electron-withdrawing group ($-I$ effect). This significantly stabilizes the carboxylate ion,making it the most acidic among the given options.
