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.
