JEE Main 2024 (31 Jan Shift 2)

Question

Choose the correct statements from the following

A. All group 16 elements form oxides of general formula EO2 and EO3 where E=S, Se, Te and Po. Both the types of oxides are acidic in nature.

B. TeO2 is an oxidising agent while SO2 is reducing in nature.

C. The reducing property decreases from H2S to H2Te down the group.

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

Correct answer
DA and B only

Step-by-step explanation

(A) All group 16 elements form oxides of the EO2 and EO3 type where E=S, Se, Te or Po. And these oxides produces acids on hydrolysis.

(B) SO2 is reducing while TeO2 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 H2S to H2Te 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
