Vedclass · Answer

(D) The acidic strength of carboxylic acids depends on the stability of the carboxylate anion formed after the loss of a proton. Electron-withdrawing groups $(EWG)$ increase acidity,while electron-donating groups $(EDG)$ decrease it.$A$. The inductive effect of the $-Cl$ atom decreases as its distance from the $-COOH$ group increases. Thus,the order is correct.$B$. $-NO_2$ is an $EWG$ (increases acidity),and $-CH_3$ is an $EDG$ (decreases acidity) compared to benzoic acid. Thus,the order is correct.$C$. The number of $-Cl$ atoms increases the electron-withdrawing effect,increasing acidity. Thus,the order is correct.$D$. Formic acid $(HCOOH)$ is more acidic than acetic acid $(CH_3COOH)$ due to the $+I$ effect of the methyl group. However,benzoic acid $(C_6H_5COOH)$ is more acidic than acetic acid $(CH_3COOH)$ because the phenyl group is electron-withdrawing relative to the methyl group. Therefore,the correct order is $HCOOH > C_6H_5COOH > CH_3COOH$. The given order $HCOOH > CH_3COOH > C_6H_5COOH$ is incorrect.

Which of the following orders of acidic strength is incorrect?
