The reaction of

HClO_{3}

with HCl gives a paramagnetic gas, which upon reaction with

O_{3}

produces

Answer: (C)

Solution

HClO_{3}

reacts with HCl to produce

ClO_{2}

(chlorine dioxide), which is paramagnetic:

HClO_{3} + HCl \to ClO_{2} + \frac{1}{2} Cl_{2} + H_{2} O

ClO_{2}

reacts with ozone (

O_{3}

) to form

Cl_{2} O_{6}

2 ClO_{2} + 2 O_{3} \to Cl_{2} O_{6} + 2 O_{2}
