Arrange the following in the order of property indicated for set : HF,HCl, HBr, HI - increasing acid strength. |
|
Answer» Solution :The relative acid strength of HF, HCI, HBr and HI depends upon their BOND dissociation enthalpies. Bond dissociation enthalpy of H-X bond DECREASES from H-F to H-I as the size of HALOGEN atom increases. Therefore, the acid strength increases in the opposite order: `HF lt HCl lt HBr lt HI` |
