Chemistry - CHEMICAL BONDING Question with Solution | TestHub

In ${\mathrm{O}}_2$, the bond order $=2$ In ${\mathrm{O}}_2^{+}$, the bond order $=2.5$ In ${\mathrm{O}}_2^{-}$, the bond order $=1.5$ In ${\mathrm{O}}_2^{-2}$, the bond order $=1$ As the bond order in ${\mathrm{O}}_2^{+}$is highest, so its internuclear distance is smallest.
