Which_of_the_following_is_the_strongest_acid1552992978.jpg image

FCH2COOH is the strongest acid out of all.

Since the electron withdrawing inductive effect (-I effect) of the halogens decreases in the order of F>Cl> Br> I , therefore the acidic strength of the α- halo acids decreases in the same order.

 

FCH2COOH  >  ClCH2COOH   >   BrCH2COOH   >   ICH2COOH.
