Question

In presence of sunlight, chlorine reacts with sulphur dioxide to give:

• A. Displacement reaction
• B. Addition reaction
• C. Substitution reaction
• D. none of these

Answer 1

The correct option is B Addition reaction

"Sulfur dioxide reacts with chlorine to give thionyl chloride($SOC{l}_2$ and dichlorine oxide ($C{l}_{2}O$). This reaction is a addition reaction.

$S{O}_2\left(g\right)+2C{l}_2\left(g\right)\to SOC{l}_2\left(g\right)+C{l}_{2}O\left(g\right)$

Hence option B is correct.
