Write a note on oxides of group-16 elements

Text Solution

Verified by Experts

The elements of group-16 form oxides of type `EO_2 `and `EO_3`. Where E = S, Se, Te or Po. `SO_(2)` is a gas while `SeO_(2)` is solid. `SO_2` is reducing while `TeO_2` is an oxidising agent. The stability of oxides decreases from `SO_2` to `TeO_2`.
Stability order: `SO_(2) gt SeO_(2) gt TeO_(2)`
Acidic strength: `SO_(2) gt SeO_(2) gt TeO_(2)`
The sulphur, selenium and tellurium also form oxides of type `EO_(3)`
For example: `SO_(3), SeO_(3), TeO_(3)`. The acidic strength decreases down the group.
Acidic strength: `SO_(3) gt SeO_(3) gt TeO_(3)`
