Vedclass · Answer

(D) Bond length is inversely proportional to bond order. The bond order for these species is calculated using Molecular Orbital Theory: Bond order of $O_2^+ = 2.5$ Bond order of $O_2 = 2.0$ Bond order of $O_2^- = 1.5$ Bond order of $O_2^{2-} = 1.0$ Since bond length $\propto \frac{1}{	ext{bond order}}$,the order of bond length is $O_2^{2-} (IV) > O_2^- (III) > O_2 (I) > O_2^+ (II)$. Thus,the correct sequence is $IV > III > I > II$.
