Which of the following statements is correct?

Options

A. `Cl_(2)` oxidises `H_(2)O` to `O_(2)` but `F_(2)` does not.
B. `Cl_(2)` is a stronger oxidising agent than `F_(2)`.
C. `F_(2)` oxidises `H_(2)O` to `O_(2)` but `Cl_(2)` does not.
D. Fluoride is a good oxidising agent.

Answer

C

Explanation

(c) : `F_(2)` is the strongest oxidising agent among the halogen group and their oxidising power decreases from `F_(2)` to `I_(2)`.
Fluorine oxidises `H_(2)O` to `O_(2)` but `Cl_(2)` reacts with water to form hydrochloric and hypochlorous acids.
`2F_(2(g)) + 2H_(2)O_((l)) to 4H_((aq))^(+) + 4F_((aq))^(-) + O_(2(g))`
`Cl_(2(g)) + H_(2)O_((l)) to HCl_((aq)) + HOCl_((aq))`
