Among the halogens, the strongest oxidising agent is:

Answer: F 2.

  • A Cl<sub>2</sub>
  • B F<sub>2</sub>
  • C Br<sub>2</sub>
  • D I<sub>2</sub>

Correct answer: B. F<sub>2</sub>

Explanation: Fluorine has the highest standard reduction potential among the halogens, making F<sub>2</sub> the strongest oxidising agent.

Electron Transfer: Zn + Cu²⁺ → Zn²⁺ + CuZnloses 2e⁻OXIDISED (Zn → Zn²⁺)2e⁻Cu²⁺gains 2e⁻REDUCED (Cu²⁺ → Cu)Zn = reducing agentCu²⁺ = oxidising agent

Electron transfer in a redox reaction: zinc loses electrons (oxidised, acts as reducing agent) and copper(II) ions gain those same electrons (reduced, acts as oxidising agent).

Concept context

Master electron transfer in chemistry: assign oxidation states, balance half-reactions, identify oxidising and reducing agents, and connect redox to everyday reactions.
