Question

SO2 reacts with Cl2 to form in the presence of sunlight to form..........​

Answer 1

Answer:

SO₂ reacts with Cl₂ to form sulphuryl chloride SO₂Cl₂ in the presence of sunlight.

Explanation:

Sulphur dioxide reacts directly with halogens to forming sulphuryl fluoride, chloride and bromide respectively.

Sulphur dioxide combines with chlorine gas in the presence of sunlight to give sulphuryl chloride  SO₂Cl₂.

        SO₂ (g)    +    Cl₂ (g)  +  hν  $\longrightarrow$    SO₂Cl₂

Sulphuryl chloride SO₂Cl₂  sometimes confused with thionyl chloride SOCl₂. But they both have different properties. SO₂Cl₂ is used as the source of chlorine Cl₂. While SOCl₂ is the source of chloride ions.

Sulphuryl chloride SO₂Cl₂  is used for the conversion of  C-H bond into C-Cl bond.
