The reaction of HClO3 with HCl gives a paramagnetic gas, which upon reaction with O3 produces
- $Cl _2 O$
- $ClO _2$
- $Cl _2 O _6$
- $Cl _2 O _7$
The Correct Option is C
Solution and Explanation
Step 1: Reaction of \( \text{HClO}_3 \) and \( \text{HCl} \)
The reaction of chloric acid (\( \text{HClO}_3 \)) with hydrogen chloride (\( \text{HCl} \)) results in the formation of chlorine dioxide (\( \text{ClO}_2 \)), which is a paramagnetic gas. This is because chlorine dioxide has an unpaired electron in its structure, making it paramagnetic. The reaction can be written as: \[ \text{HClO}_3 + \text{HCl} \rightarrow \text{ClO}_2 + \text{H}_2\text{O} \]
Step 2: Reaction of \( \text{ClO}_2 \) with \( \text{O}_3 \)
When chlorine dioxide (\( \text{ClO}_2 \)) reacts with ozone (\( \text{O}_3 \)), it forms dichlorine hexaoxide (\( \text{Cl}_2\text{O}_6 \)). The reaction can be written as: \[ 2 \text{ClO}_2 + \text{O}_3 \rightarrow \text{Cl}_2\text{O}_6 \] This reaction shows that \( \text{ClO}_2 \) reacts with ozone to form the compound \( \text{Cl}_2\text{O}_6 \).
Step 3: Conclusion
Based on the reactions described above, the correct compound formed after the reaction of the paramagnetic gas with \( \text{O}_3 \) is \( \text{Cl}_2\text{O}_6 \), which corresponds to option C.
The correct option is C: \( \text{Cl}_2\text{O}_6 \).

Questions Asked in JEE Advanced exam
The center of a disk of radius $ r $ and mass $ m $ is attached to a spring of spring constant $ k $, inside a ring of radius $ R>r $ as shown in the figure. The other end of the spring is attached on the periphery of the ring. Both the ring and the disk are in the same vertical plane. The disk can only roll along the inside periphery of the ring, without slipping. The spring can only be stretched or compressed along the periphery of the ring, following Hooke’s law. In equilibrium, the disk is at the bottom of the ring. Assuming small displacement of the disc, the time period of oscillation of center of mass of the disk is written as $ T = \frac{2\pi}{\omega} $. The correct expression for $ \omega $ is ( $ g $ is the acceleration due to gravity):

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
