Which of the following statements concerning the oxidizing power and electrode potentials of halogen — p Block Elements Chemistry Question

💡 Solution & Explanation

$F_2$ is the strongest oxidizing agent (oxidizes water to $O_2$). Its high oxidizing power results from low bond dissociation energy and very high hydration enthalpy of the small $F^-$ ion. Standard reduction potential decreases from F to I, so $I_2$ is the weakest and cannot oxidize $Br^-$ to $Br_2$.
