Solution

Order of decreasing acidity of given compounds based on $p K_{a}$ :
$C F_{3} C O O H > H C F_{2} C O O H > C F H_{2} C O O H > N O_{2} C H_{2} C O O H > C C l_{3} C O O H > H C C l_{2} C O O H > H_{2} C C l C O O H > H_{2} C B r C O O H > C_{6} H_{5} C O O H > C_{6} H_{5} C H_{2} C O O H > H C O O H > C H_{3} C O O H > C H_{3} C H_{2} C O O H .$
