HOW THE ACIDIC STRENGTH OF DERIVATIVE OF CARBOXYLIC ACIDS VARY . GIVE IN DETAIL

Please don't your questions twice..

Dear student,

The more powerful and the more the number of such substituents and the closer they are to the carboxyl group, the greater is the inductive effect.

The FCH₂COOH > ClCH₂COOH > Br CH₂COOH > ICH₂COOH > CH₂COOH.

The electronegativity and thus the electron withdrawing power of the halogen substituent and thus the strength of the acid decreases in the given order.

CH₃CCOOH > Cl₂CHCOOH > ClCH₂COOH > CH₃COOH

The number of electron withdrawing chloro group and thus the acid strength decreases in this order.

CH₃CH₂CH(Cl)COOH > CH₃CHCl CH₂ COOH > ClCH₂CH₂CH₂COOH > CH₃CH₂CH₂ COOH

The inductive effect decreases rapidly with increasing distance from the carboxylic group and so does the acid strength.
