Question

Choose the correct statements from the following

A. All group $16$ elements form oxides of general formula $E O_{2}$ and $E O_{3}$ where $E = S, S e, T e$ and $P o$ . Both the types of oxides are acidic in nature.

B. $T e O_{2}$ is an oxidising agent while $S O_{2}$ is reducing in nature.

C. The reducing property decreases from $H_{2} S$ to $H_{2} T e$ down the group.

D. The ozone molecule contains five lone pairs of electrons.

(A) All group 16 elements form oxides of the E O 2 and E O 3 type where E = S , S e , T e or P o . And these oxides produces acids on hydrolysis. (B) S O 2 is reducing while T e O 2 is an oxidising agent. An oxidising agent is a substance that causes oxidation by accepting electrons; therefore, it gets reduced. A reducing agent is a substance that causes reduction by losing electrons; therefore, it gets oxidised. (C) The reducing property increases from H 2 S to H 2 T e down the group. This is because the bond energy E - H ( E = S , Se , Te ) bond decreases down the group. (D) have six lone pairs
