JEE Advanced 2025 — Paper 2 — Question 34

The complete hydrolysis of $\mathrm{ICl}, \mathrm{ClF}_{3}$ and $\mathrm{BrF}_{5}$ , respectively, gives

Option A:
$\mathrm{IO}^{-}, \mathrm{ClO}_{2}^{-}$ and $\mathrm{BrO}_{3}^{-}$
Correct
Option B:
$\mathrm{IO}_{3}^{-}, \mathrm{ClO}_{2}^{-}$ and $\mathrm{BrO}_{3}^{-}$
Option C:
$\mathrm{IO}^{-}, \mathrm{ClO}^{-}$ and $\mathrm{BrO}_{2}^{-}$
Option D:
$\mathrm{IO}_{3}^{-}, \mathrm{ClO}_{4}^{-}$ and $\mathrm{BrO}_{2}^{-}$

Answer: A

Step-by-step solution

$\xrightarrow{\mathrm{ICl} \xrightarrow{\mathrm{H}_{2} \mathrm{O}}} \underset{\mathrm{IO}^{\ominus}}{\mathrm{HIO}}+\mathrm{HCl}$

$\mathrm{ClF}_{3} \xrightarrow{\mathrm{H}_{2} \mathrm{O}} \underset{\substack{\downarrow \\ \mathrm{ClO}_{2}^{\ominus}}}{\mathrm{HClO}_{2}}+3 \mathrm{HF}$

$\mathrm{BrF}_{5} \xrightarrow{\mathrm{H}_{2} \mathrm{O}} \underset{\substack{\downarrow \\ \mathrm{BrO}_{3}}}{\mathrm{HBrO}_{3}}+5 \mathrm{HF}$
