List of top Chemistry Questions on Chlorine

In which of the following reactions, chlorine undergoes disproportionation? \[ \begin{aligned} \text{I.} \quad & \text{Reaction with cold, dilute NaOH} \\ \text{II.} \quad & \text{Reaction with hot, concentrated NaOH} \\ \text{III.} \quad & \text{Reaction with } \mathrm{H_2S} \end{aligned} \] The correct answer is

Chlorine oxidises sulphur dioxide in the presence of water to give an oxyacid $A$. Chlorine also oxidises iodine in the presence of water to give an oxyacid $B$. The oxidation states of $S$ and $I$ in $A$ and $B$ are respectively

$X Cl _{2}( excess )+Y Cl _{2} X Cl _{4}+Y \downarrow$ $Y O {->[{\Delta}][{>400^{\circ} C }]} \frac{1}{2} O _{2}+Y$ Ore of Y would be ,
