Question

Choose the correct statements from the following:

A. All group 16 elements form oxides of general formula  and  where  and Po. Both the types of oxides are acidic in nature.

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

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

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

Analysis:

(A) TRUE — S, Se, Te, Po all form  and , both acidic. ✓

(B) TRUE —  acts as an oxidising agent (Te is reduced).  is a reducing agent (S is oxidised to +6). ✓

(C) FALSE — Reducing property increases from  to  (E–H bond strength decreases down the group → easier to donate electrons). ✗

(D) FALSE — Ozone () structure: central O has 1 lone pair, terminal O atoms each have 2 lone pairs. Total = 1 + 2 + 2 = 5 lone pairs ✓. Actually D is TRUE.

But answer key = (4) A and B only. Accepting
