Q:

Which of the following is the strongest acid?

A) ClCH2COOH	B) BrCH2COOH
C) FCH2COOH	D) ICH2COOH

Answer & 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 of F>Cl> Br> I , therefore the acidic strength of the α- halo acids decreases in the same order.

FCH₂COOH > ClCH₂COOH > BrCH₂COOH > ICH₂COOH.
