Vedclass · Answer

(A) The acid strength of carboxylic acids depends on the stability of the conjugate base (carboxylate ion). Electron-withdrawing groups $(EWG)$ increase acidity by stabilizing the negative charge,while electron-donating groups $(EDG)$ decrease acidity by destabilizing it. The compounds are: $(A) CH_3CO_2H$ (Acetic acid) $(B) MeOCH_2CO_2H$ (Methoxyacetic acid,$-OCH_3$ is $EWG$) $(C) CF_3CO_2H$ (Trifluoroacetic acid,$-CF_3$ is a very strong $EWG$) $(D) (CH_3)_2CHCO_2H$ (Isobutyric acid,isopropyl group is $EDG$) Comparing the effects: $(D)$ has an isopropyl group (strongest $EDG$),making it the least acidic. $(A)$ has a methyl group (weak $EDG$). $(B)$ has a methoxy group $(EWG)$. $(C)$ has three fluorine atoms (strongest $EWG$). The order of increasing acid strength is $D < A < B < C$.

The correct order of increasing acid strength of the compounds is:
$(A) CH_3CO_2H$
$(B) MeOCH_2CO_2H$
$(C) CF_3CO_2H$
$(D) (CH_3)_2CHCO_2H$
