Vedclass · Answer

(B) The $pK_a$ value is inversely proportional to the acid strength. $A$ higher $pK_a$ value indicates a weaker acid. Comparing the given acids: $FCH_2COOH$ is the strongest due to the strong $-I$ effect of $F$. $ClCH_2COOH$ is the next strongest due to the $-I$ effect of $Cl$. $HCOOH$ is stronger than $CH_3COOH$ because the $CH_3$ group in $CH_3COOH$ exerts a $+I$ effect,which destabilizes the carboxylate ion. Therefore,$CH_3COOH$ is the weakest acid among the given options and has the highest $pK_a$ value.
