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

The Correct Option is D

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.
