Standard reduction potentails of the half reactions are given below: `F_(2)(g)+2e^(-) rarr 2F^(-)(aq.),, E^(ɵ)= +2.87` `Cl_(2)(g)+2e^(-) rarr 2Cl^(-)(aq.),, E^(ɵ)= +1.36 V` `Br_(2)(g)+2e^(-) rarr 2Br^(-)(aq.),, E^(ɵ)= +1.09 V` `I_(2)(s)+2e^(-) rarr 2l^(-)(aq.),, E^(ɵ)= +0.54 V` The strongest oxidizing and reducing agents respectively are:A. `Cl_(2)` and `Br^(-)`B. `Cl_(2)` and `I_(2)`C. `F_(2)` and `I^(-)`D. `Br_(2)` and `Cl^(-)` |

Answer» Correct Answer - C Higher the reduction potential more easily it is reduced and hence stronger is the oxidising agent. `F_(2)` has highest reduction potential. `therefore F_(2)` is the strongest oxidising agent. Considering the reverse reaction (oxidiation reactions). higher the oxidiation potential more easily it is oxidised and hence stronger is the reducing agent. Oxidation potential `1(-0.53V)` is highest out of 2.85,-1.36,-1.36 and 0. 53, Hence I is the strongest reducing agent. |
