Question

Choose the correct statements from the following:
A. All group 16 elements form oxides of general formula $EO_2$ and $EO_3$ where $E = S, Se, Te,$ and Po. Both the types of oxides are acidic in nature.
B. TeO$_2$ is an oxidising agent while SO$_2$ is reducing in nature.
C. The reducing property decreases from H$_2$S to H$_2$Te down the group.
D. The ozone molecule contains five lone pairs of electrons.
Choose the correct answer from the options given below:

• A. A and D only
• B. B and C only
• C. C and D only
• D. A and B only

Answer 1

Answer: (D)

A and B only

Answer 2

Statement A is true as all group 16 elements form $EO_2$ and $EO_3$ oxides, and these oxides are generally acidic.

Statement B is true as $TeO_2$ acts as an oxidising agent, while $SO_2$ is a reducing agent.

Statement C is false. The reducing nature actually increases as we move down the group.

Statement D is false as the ozone molecule $O_3$ contains only three lone pairs of electrons on each oxygen atom.
