Question
Fluorine is a stronger oxidising agent than chlorine. Why?
Solution
The oxidising power of halogens decreases as we go down the group. The electrode potential of F2 is +2.87 V, while that of Cl2 is +1.36 V. This means that fluorine can be reduced more easily than chlorine. Therefore, fluorine is the strongest oxidising agent.

Statement I: Acid strength increases in the order given as HF << HCl << HBr << HI.
Statement II: As the size of the elements F, Cl, Br, and I increase down the group, the bond strength of HF, HCl, HBr and HI decreases and so the acid strength increases.
