Among halogens, F_(2) is the strongest oxidising agent. Or F_(2) is a strong oxidising agent in the 17th group. |

Answer» Solution :The standard electode potentials of halogens are : `F_(2) + 2 E^(-) rarr 2 F^(-), E^(@) = + 2.87 V and Cl_(2) + 2E^(-) rarr 2 Cl^(-), E^(@) = + 1.36 V` `Br_(2) 2e^(-) rarr 2 Br^(-), E^(@) = + 1.09 V and I_(2) + 2e^(-) rarr 2 I^(-), E^(@) = + 0.54 V` Since `E^(@)` for `F_(2)//F^(-)` ELECTRODE is the maximum, `F_(2)` is REDUCED most readily. In other words, `F_(2)` is the stongest oxidising AGENT. |
