Answer : 3. "FCH2COOH"
Explanation :
Answer: C) FCH2COOH Explanation: FCH2COOH is the strongest acid out of all .Since the electron withdrawing inductive effect (-I effect) of the halogens decreases in the order F>Cl> Br> I , therefore the acidic strength of the α- halo acids decreases in the same order. FCH2COOH > ClCH2COOH > BrCH2COOH > ICH2COOH.
