The reaction of

{HClO}_{3}

with

HCl

gives a paramagnetic gas, which upon reaction with

{O}_{3}

produces

Options

A ${Cl}_{2}O$
B ${ClO}_{2}$
C ${Cl}_{2}{O}_{6}$
D ${Cl}_{2}{O}_{7}$

Correct answer

C. ${Cl}_{2}{O}_{6}$

Step-by-step solution

${HClO}_{3}$ reacts with $HCl$ according to the following equation,
$2{HClO}_{3} + 2HCl ⟶ 2{ClO}_{2} + {Cl}_{2} + 2{H}_{2}O$
${ClO}_{2}$ molecule is paramagnetic, as it contains odd number of electrons.
$2{ClO}_{2} + 2{O}_{3} ⟶ {Cl}_{2}{O}_{6} + 2{O}_{2}$
ClO₂ is used as a bleaching agent for paper pulp and textiles and in water treatment
