The reaction of HClO 3 with HCl gives a paramagnetic gas, which upon reaction with O 3 produces

Options

  1. ACl 2 O
  2. BClO 2
  3. CCl 2 O 6
  4. DCl 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 + 2 HCl ⟶ 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 ClO 2 is used as a bleaching agent for paper pulp and textiles and in water treatment
