$HF$

Vedclass · Answer

(B) The $pK_a$ value is inversely proportional to the acid strength. Stronger acids have lower $pK_a$ values. The order of acid strength for hydrohalic acids is $HF The corresponding $pK_a$ values are: $HF$ $(pK_a \approx 3.1)$ $HCl$ $(pK_a \approx -6.0)$ $HBr$ $(pK_a \approx -9.0)$ $HI$ $(pK_a \approx -9.5)$ Thus,$HF$ is the weakest acid among the given options and possesses the highest $pK_a$ value. Therefore,the correct option is $(B)$.

Which acid among the following has the highest $pK_a$ value?
