उत्तर
F - CH2COOH, O2N - CH2 COOH CH3 COOH,HCOOH - acid character.
CH3COOH < HCOOH < F - CH2 COOH < NO2 CH COOH
Methyl group in CH3 COOH decreases acidity due to its electron withdrawing nature, hence less acidic than formic acid whereas electron withdrawing group, group NO2 and F shows greater acidity with FCH2 COOH highest due to strongly electronegative fluorine group
