Answer» `F_(2)` and `I^(-)` `Br_(2)` and `Cl^(-)` `Cl_(2)` and `Br^(-)` `Cl_(2)` and `I_(2)`. SOLUTION :(a) More negative (or less positive) the VALUE of reduction potential, stranger will be the reducing agent. Thus `L^(-)` is the STRONGEST reducing agent. More positive is the values of reduction potential, stronger will be the oxidising agent. Thus, `F_(2)` is the strongest oxidising agent.
