In the oxyacids of chlorine, ClâO bond contains:
Show Hint
In ClâO bonds of oxyacids, the bonding involves both sigma and pi bonds, with the pi bonding arising from sideways overlap of p-orbitals.

- \( \pi \)-\( \pi \) bonding
- \( \pi \)-\( \sigma \) bonding
- \( \sigma \)-\( \pi \) bonding
- None of the above

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understand the bonding in oxyacids of chlorine.
In oxyacids of chlorine, such as chloric acid (\( \text{HClO}_3 \)), the ClâO bond involves both sigma and pi bonding. The sigma bond is formed by the overlap of orbitals along the internuclear axis, while the pi bond involves the sideways overlap of p-orbitals.
Step 2: Analyze the types of bonding.
- \( \pi \)-\( \pi \): This type of bonding occurs between two parallel p-orbitals, but it is not involved in ClâO bonds in chlorine oxyacids.
- \( \pi \)-\( \sigma \): This is the correct description for the ClâO bond, where a sigma bond and a pi bond are formed due to the hybridization and electron overlap.
- \( \sigma \)-\( \pi \): This would imply that the sigma bond is formed before the pi bond, which is incorrect in this case.
- None of the above: This is incorrect since the correct bonding type is \( \pi \)-\( \sigma \).
Step 3: Conclusion.
The correct answer is (2), \( \pi \)-\( \sigma \) bonding, which is present in the ClâO bond of chlorine oxyacids.
