1 . A since chlorine is electron withdrawing group & nearer the chlorine group will inc. acidity of carboxylic group more. As the distance inc. The - I effect decreases and thus 2chloro butanoic acid is more acidic than 3 chloro butanoic acid which in turn more acidic than 4chlorobutanoic acid.
2. 4 is not a good method.
3. 4 is the final product.
