Reason: Covalent radius of is some what oxidising agent. larger than sulphur.
View answer and explanation
Correct option: B
If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion
Option B is correct. SO2 has a bent shape at room temperature, and SeO2 also has a bent shape in the vapor phase at higher temperatures. The covalent radius difference is true but doesn't directly explain the shape similarity.
