$HF$

Vedclass · Answer

(A) The acidic strength of hydrohalic acids increases down the group: $HF This is because the bond dissociation enthalpy decreases as the size of the halogen atom increases,making it easier to release the $H^{+}$ ion.$HF$ is the weakest acid because of the strong $H-F$ bond and the presence of strong intermolecular $H$-bonding,which restricts the release of $H^{+}$ ions.Therefore,the correct option is $A$.
