Question

Choose the correct statements from the following:

A. All group 16 elements form oxides of general formula $\mathrm{EO_2}$ and $\mathrm{EO_3}$ where $\mathrm{E = S, Se, Te}$ and Po. Both the types of oxides are acidic in nature.

B. $\mathrm{TeO_2}$ is an oxidising agent while $\mathrm{SO_2}$ is reducing in nature.

C. The reducing property decreases from $\mathrm{H_2S}$ to $\mathrm{H_2Te}$ down the group.

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

Choose the correct answer from the options given below:

A and B only. Strategy: Evaluate the accuracy of statements regarding Group 16 elements and Ozone properties. Step 1: Statement Analysis - A: True. S, Se, Te, Po form dioxides and trioxides. They are generally acidic (though heavier dioxides are amphoteric). - B: True. Down the group, reducing character of dioxides decreases and oxidizing character increases. SO2 is a reducing agent while TeO2 acts as an oxidant. - C: False. Reducing property of hydrides increases from H2S to H2Te as M-H bond dissociation enthalpy decreases. - D: False. The Ozone molecule (O3) contains 6 lone pairs (1 on central, 2 and 3 on outer oxygens). Step 2: Conclusion Only statements A and B are correct. {{Answer: (Option) [d] A and B only}}
