Identify $\mathrm{X}, \mathrm{Y}$ and Z in the following reaction. (Equation not balanced) $\mathrm{ClO}+\mathrm{NO}_{2} \rightarrow \underline{\mathrm{X}} \xrightarrow{\mathrm{H}_{2} \mathrm{O}} \underline{\mathrm{Y}}+\underline{\mathrm{Z}}$

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

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

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

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

Identify

X, Y

and Z in the following reaction.
(Equation not balanced)

ClO + NO_{2} \to \underline{X} H_{2} O \underline{Y} + \underline{Z}

Answer: (C)

The chlorine monoxide radical combines with nitrogen dioxide to give chlorine nitrate,

ClONO X_{2}

, which is X. On hydrolysis this molecule cleaves to give hypochlorous acid,

HOCl

(Y), and nitric acid,

HNO X_{3}

(Z). Thus X is

ClONO X_{2}

, Y is

HOCl

and Z is

HNO X_{3}
