MCQ
What is the correct order of acidity for the following carboxylic acids: CH3COOH, ClCH2COOH, Cl2CHCOOH, Cl3CCOOH?
Chemistry
A CH3COOH > ClCH2COOH > Cl2CHCOOH > Cl3CCOOH
B Cl3CCOOH > Cl2CHCOOH > ClCH2COOH > CH3COOH
C All have the same acidity
D ClCH2COOH > Cl3CCOOH > Cl2CHCOOH > CH3COOH
Explanation

Chlorine is electron-withdrawing (inductive effect). More Cl atoms increase acidity by stabilizing the conjugate base (carboxylate anion) through electron withdrawal.
