Vedclass · Answer

(B) The stability of a species is directly proportional to its bond order.Using Molecular Orbital Theory $(MOT)$,the bond orders are calculated as follows:$O_2^{+}$: Bond order = $(10 - 5) / 2 = 2.5$$O_2$: Bond order = $(10 - 6) / 2 = 2.0$$O_2^{-}$: Bond order = $(10 - 7) / 2 = 1.5$$O_2^{2-}$: Bond order = $(10 - 8) / 2 = 1.0$Since $O_2^{2-}$ has the lowest bond order of $1.0$,it is the least stable species among the given options.

Which of the following species is the least stable?
