Choose the correct statements from the following

A. All group 16 elements form oxides of general formula EO2\mathrm{EO}_2 an EO3\mathrm{EO}_3, where E=S,Se,Te\mathrm{E}=\mathrm{S}, \mathrm{Se}, \mathrm{Te} and Po. Both the types of oxides are acidic in nature.

B. TeO2\mathrm{TeO}_2 is an oxidising agent while SO2\mathrm{SO}_2 is reducing in nature.

C. The reducing property decreases from H2 S\mathrm{H}_2 \mathrm{~S} to H2Te\mathrm{H}_2 \mathrm{Te} down the group.

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

Choose the correct answer from the options given below:
View answer and explanation
Correct option: D
A and B only
Option D (if both Assertion & Reason are false) is correct because when two volatile liquids are mixed, the vapor pressure of both components can increase or decrease depending on the interactions, and the vapor pressure of the solution can also increase or decrease.
