Explain the nature of oxides of group-16 elements. |
|
Answer» Solution :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)` |
