Group or atom attached with -COOH group shows positive inductive effect increases electron density on oxygen atom, which suppress the ionisation of H+, hence, acidic strength decreases. Group or atom attached with -COOH group shows negative inductive effect decreases electron density on oxygen atom, which facilitate the ionisation of H+, hence acidic strength increases. Sequence of group shows negative inductive effect. - CHCl 2>- CH 2 F >- CH 2 Cl - CH 3 group shows positive inductive effect and -H doesn't show any effect. So, > ClCH 2 COOH > HCOOH > CH 3 COOH
