Chemistry - CHEMICAL BONDING Question with Solution | TestHub

LUMO level for${\mathrm{C}}_2$molecule is${\mathrm{\sigma }}_{2\mathrm{p}\mathrm{x}}$orbital.

In${\mathrm{C}}_2$molecules both the bonds$\mathrm{\pi }$are bonds

In${\mathrm{C}}_2^{2-}$ion there is one$\mathrm{\sigma }$and two$\mathrm{\pi }$bonds

${\mathrm{C}}_2$is paramagnetic but${\mathrm{C}}_2^{2-}$is diamagnetic.
