Q. For the following carboxylic acids,
(i) $F_3CCOOH$ (ii) $CH_3COOH$ (iii) $C_6H_5COOH$ (iv) $CH_3CH_2COOH$
The correct order of $pK_{a}$ values is

AIIMSAIIMS 2019Aldehydes Ketones and Carboxylic Acids

Solution:

As we know that stronger the acid, lower the value of $pK_a $.
Hence the correct order of $pK _{ a }$ value is- $ 4 >2 >3 >1$
