GOOD MORNING;-)
HERE IS YOUR ANSWER :-------
CHLOROAETIC ACID IS MORE STRONGER THAN ACETIC ACID BECAUSE OF THE ELECTRONS WITHDRAWING EFFECT OF CHLORINE.YHOS EFFECT IS CAUSED BY ELECTRONEGATIVITY OF CHLORINE.THE WITHDRAWING EFFECT MEANS THE NEGATIVE CHARGE CARRIED ON THE ACETATE ION S.THIS ULTIMATELY CAUSES A GREATER DEGREE OF IONIZATION LEADING TO A LOWER PH.

Answer
________
1. 2Cl3 C-COOH is more acidic than H3C-COOH due to the cumulative -Ieffect of three Cl atoms attached to C atom next to the COOH group.
2. As a result of the -I effect (pulling of elctrons of bobd between Cl and Catom) of Cl atoms, C atom of COOH group develops +ve charge. To compensate the electron deficiency, the C atom of the COOH group, in turn, tends to pull the the shared electons pair between C and O atom of O-H group with more power than in H3C-COOH, thus giving more H+ ions in the aqueous solution.
Hence,Cl3C- COOH is more acidic than
CH3COOH.
