Identify X, Y and Z in the following reaction. (Equation not balanced)

\(\mathrm{Cl}\overset{˙}{\mathrm{O}}+{\mathrm{NO}}_{2}\to \underset{¯}{\mathrm{X}}\overset{{\mathrm{H}}_{2}\mathrm{O}}{\to }\underset{¯}{\mathrm{Y}}+\underset{¯}{\mathrm{Z}}\)

[JEE Main 2023, 31 Jan (Shift 1)]

a

\(\mathrm{X}={\mathrm{ClONO}}_{2},\mathrm{Y}=\mathrm{HOCl},\mathrm{Z}={\mathrm{NO}}_{2}\)

b

\(\mathrm{X}={\mathrm{ClNO}}_{2},\mathrm{Y}=\mathrm{HCl},\mathrm{Z}={\mathrm{HNO}}_{3}\)

c

\(\mathrm{X}={\mathrm{ClONO}}_{2},\mathrm{Y}=\mathrm{HOCl},\mathrm{Z}={\mathrm{HNO}}_{3}\)

d

\(\mathrm{X}={\mathrm{ClNO}}_{3},\mathrm{Y}={\mathrm{Cl}}_{2},\mathrm{Z}={\mathrm{NO}}_{2}\)

✓ Correct answer: c)

\(\mathrm{X}={\mathrm{ClONO}}_{2},\mathrm{Y}=\mathrm{HOCl},\mathrm{Z}={\mathrm{HNO}}_{3}\)

Explanation

(c) The reaction occurs as:

\(\mathrm{Cl}\overset{˙}{\mathrm{O}}+{\mathrm{NO}}_{2}⟶\underset{(\mathrm{X})}{\mathrm{ClO}}\overset{+{\mathrm{H}}_{2}\mathrm{O}}{\to }\underset{(\mathrm{Y})}{\mathrm{HOCl}}+\underset{(\mathrm{Z})}{{\mathrm{HNO}}_{3}}\)
