Question

Which of the following statements is not correct for $S{O}_2$ gas?

• A. It acts as bleaching agent in moist conditions.
• B. Its dilute solution is used as disinfectant.
• C. Its molecules have linear geometry.
• D. Acidified $KMn{O}_4$ is decolourised when $S{O}_2$ is passed through it.

Answer 1

The correct option is C Its molecules have linear geometry.

The shape of $S{O}_2$ is bent shape and approximate bond angle is 120 degrees with asymmetric charge distribution on the central atom that is on sulfur.

So the given option C is a wrong statement.$S{O}_2$ shape is bent not linear.

Hnce option C is correct.
