Inorganic chemistry: Oxidising Strength of Halogen?

[ban]

Here's the question:

Arrange Cl2, Br2, Br- in the ascending order of their oxidising strengths.

Thanks

This means which is the best oxidizing agent, which means itself becomes reduced and gains electrons.

Cl is the most electronegative so it would be the strongest.
Br- would be a lousy oxizing agent because it cant easily gain an electron because it would be Br-2.

So this is your increasing order of oxidising strenghths

Br-, Br2, Cl2
