Chemistry - CHEMICAL BONDING Question with Solution | TestHub

${\mathrm{KO}}_2$ and ${\mathrm{K}}_2{\mathrm{O}}_2$ are diamagnetic while ${\mathrm{O}}_2$ is paramagnetic.

${\mathrm{KO}}_2$ and ${\mathrm{O}}_2$ are paramagnetic while ${\mathrm{K}}_2{\mathrm{O}}_2$ is diamagnetic.

Bond length increases in the order : ${\mathrm{O}}_2<{\mathrm{O}}_2^{-}<{\mathrm{O}}_2^{2-}$.

Bond enthalpy decreases in the order : ${\mathrm{O}}_2>{\mathrm{O}}_2^{-}>{\mathrm{O}}_2^{2-}$.
