Question

Give the correct order of initials T or F for following statements. Use T if statement is true and F if it is false.
(I) Number of S—S bonds in H2SnO6 are (n + 1)
(II) When F2 reacts with water gives HF, O2 and O3
(III) LiNO3 and BaCl2 compounds are used in fire works
(IV) Be and Mg hydrides are ionic and polymeric

Correct answer: A. Step 1: For an ion to undergo both oxidation and reduction (i.e., disproportionate or act as both an oxidizing and reducing agent), the central element must be in an intermediate oxidation state, rather than its maximum or minimum oxidation state. Step 2: In Cr2O7^2-, Cr is in its maximum +6 state (only reduction possible). In NO3^-, N is in its maximum +5 state. In S^2-, S is in its minimum -2 state (only oxidation possible). In OCl^- (hypochlorite), Cl is in the +1 oxidation state, which is intermediate between its limits of -1 and +7. Step 3: Thus, OCl^- can undergo both oxidation (to ClO3^- or ClO4^-) and reduction (to Cl^-), making option (c) the correct choice.
