Important Compounds of Group 17 Elements

The products obtained from the following chemical reactions are respectively

(i) $\underset{\left(\text{hot}\text{and}\text{conc}\text{.}\right)}{\text{NaOH}}+{\text{Cl}}_2\to$

(ii)  $\underset{\left(\text{excess}\right)}{{\text{XeF}}_{\text{6}}}{+\text{H}}_2\text{O}\to$

Given below are two statements : one is labelled as Assertion $\left(\mathrm{A}\right)$ and the other is labelled as Reason $\left(\mathrm{R}\right)$.

Assertion $\left(\mathrm{A}\right)$: $\mathrm{ICl}$ is more reactive than ${\mathrm{I}}_2$.

Reason $\left(\mathrm{R}\right)$: $\mathrm{I}-\mathrm{Cl}$ bond is weaker than $\mathrm{I}-\mathrm{I}$ bond. In the light of the above statements, choose the most appropriate answer from the options given below: (1) Both $\left(\mathrm{A}\right)$ and $\left(\mathrm{R}\right)$ are correct but $\left(\mathrm{R}\right)$ is not the correct explanation of $\left(\mathrm{A}\right)$.

This question concerns the elements of group $17-$ fluorine, chlorine, bromine and iodine. When sodium chloride is treated with concentrated sulphuric acid, a colourless gas, $\mathrm{X},$ which fumes in moist air, is formed. When sodium iodide is treated in the same way a coloured vapour, $\mathrm{Y},$ is product. If $90\%$ phosphoric acid is used instead of sulphuric acid, a colourless gas is produced in each reaction.

Behaviour of ${\mathrm{H}}_2{\mathrm{SO}}_4$ and ${\mathrm{H}}_3{\mathrm{PO}}_4$ is different towards $\mathrm{NaI}$ because:

This question concerns the elements of group $17-$ fluorine, chlorine, bromine and iodine. When sodium chloride is treated with concentrated sulphuric acid, a colourless gas, $\mathrm{X},$ which fumes in moist air, is formed. When sodium iodide is treated in the same way a coloured vapour, $\mathrm{Y},$ is formed as a product. Gases $\mathrm{X}$ and $\mathrm{Y}$ are respectively
