Question

Which of the following statement(s) is/are correct regarding group $16$ oxides?

• A. All the elements form ​two types of oxides​, $E{O}_2$ and $E{O}_3$
• B. Trioxides act only as oxidising agents
• C. Both dioxides​ and trioxides are ​acidic in nature
• D. Dioxides act only as reducing agents

Answer 1

Answer: (A), (B), (C)

Both dioxides​ and trioxides are ​acidic in nature

All the group $16$ elements form ​two types of oxides​, $E{O}_2$ and $E{O}_3$ where $E=S,Se,Te,Po$. Both dioxides​ and trioxides are ​acidic in nature.
$S{O}_2$ is a reducing agent while $Te{O}_2$ is an oxidising agent but trioxides of group $16$ act only as oxidising agents.
Hence, (a), (b) and (c) are correct.
