Question

Why Sulphur Dioxide are gases while Selenium dioxide are solid​

Answer 1

Answer:

Explanation:

Sulphur Dioxide ( SO₂ ) is a gas because it is molecular and its molecules dont have as such any force present between them .

Whereas

Selenium Dioxide ( SeO₂ ) has a chain of polymeric structure consisting of alternate Selenium and oxygen atoms

Answer 2

Sulphur dioxide is gas because its separate entity and selenium dioxide is solid because it's a polymer.

Explanation:

• The sulphur and selenium both are members of group 16 with 6 electrons in its outer shell.

• The sulphur and oxygen bonds in sulphur dioxide are one sigma bond and the other is p pi - p pi bond.

• So its stable.

• But the d pi d pi bonds in selenium dioxide isn't stable at all.

• So they form a sheet of 2D polymer instead of single molecules.

• So the sulphur dioxide is gas while selenium dioxide is solid.
