Acid Strength?

0 ⤊

(a)ethanoic acid.
(b)methoxyethanoic acid.
(c)trifluroethanoic acid.
Arrange in the order of increasing acid strength.

trifluroethanoic acid is a stronger acid than ethanoic acid because of negative inductive effect of electron withdrawing flourine atoms.

How to explain da acid strength of methoxyethanoic acid w.r.t the other two compounds? Plz Help.

methoxy means that it has a CH3O- susbtituent.
Think of it like a -OH group for simplicity. The negative inductive effect of O will make the acid stronger than the non-substituted. However the effect is not as strong as that of three fluorine atoms.
Thus the methoxy-acid will be in between the two.
