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
