Which of the following it the most stable acid ? – InterviewSolution

1.	Which of the following it the most stable acid ?
Answer» `CH_(2)(F) COOH` <BR>`CH_(2)(Br) COOH` `CH_(2)(Cl) COOH` `CH_(2)(I) COOH` Solution :Electron withdrawing GROUPS or atoms increase the strength of acid. More the elec TRON withdrawing power, more the strength of acid. In halogens electron withdrawing power is , ` F gt Cl gt Br Gt I`. Hence, `CH_(2)ICOOH` is stable acid.
