Write the preparation of interhalogen compounds and state their uses. Discuss the properties of interhalogen compounds.

When cold and dilute $NaOH$ reacts with $Cl_2$, which of the following is formed?

The chief source of iodine in which it is present as sodium iodate is

Given below are two statements: Statement $(I)$: Oxidising power of halogens decreases in the order $F_2 > Cl_2 > Br_2 > I_2$, which is the basis of "Layer test". Statement $(II)$: "Layer test" to identify $Br_2$ and $I_2$ in aqueous solution involves the oxidation of bromide or iodide into $Br_2$ or $I_2$ respectively with $Cl_2$, which is a type of displacement redox reaction. In the light of the above statements, choose the correct answer from the options given below:

Mark the strongest acid.
