Question

Which of the following is the strongest oxidising agent ?
A. Cl2 B. F2
C. I2 D. Br2

Answer 1

Answer:

fluorine

fluorineThe strongest oxidizing agent is fluorine with the largest positive number for standard electrode potential.

Answer 2

Answer:

The correct answer is option B

Fluorine acts as a strong oxidizing agent.

Explanation:

F2 is a very strong oxidizing agent due to which it displaces oxygen from water.

Fluorine as a strong oxidizing agent

• When a halogen has low energy of dissociation, a high electron affinity, and higher hydration of its ion, it will have high oxidizing power.
• Fluorine has although low electron affinity than Chlorine but low dissociation energy and have high hydration energy of its ion, therefore Fluorine is the strongest oxidizing agent.
• Fluorine is more electronegative therefore it can attract a shared pair of an electron more easily and strongly than other halogens.
• Fluorine is a oxidizing agent because it has a higher reduction potential (more ability to lose electrons).
• The tendency of losing electrons assigned to Fluorine is due to its electronegativity of it.
• Hence fluorine acts as a strong oxidizing agent.
