Which of the following represents the correct order of the acidity in the given compounds ?

The order of acidity of compounds depends on the electron withdrawing substituent. Among halogens, the order of electronegativity is as follows- 3 F>Cl>Br>CH Thus, the –I effect decreases and hence the acidity decreases. Thus, the correct option is (d) 2 2 2 3 FCH COOH>ClCH COOH>BrCH COOH>CH COOH
