Calcium carbide exists as Ca2+ and C22- According to the molecular orbital model, C22- should have a bond order of 3 (configuration πu2 π2u σ2g). MOT configuration suggests that it contains one σ and two π-bonds

Q. The number of types of bonds between two carbon atoms in calcium carbide is:

One sigma, one pi

Two sigma, one pi

Two sigma, two pi

One sigma, two pi

Calcium carbide exists as $C a^{2 +}$ and $C_{2}^{2 -}$ According to the molecular orbital model, $C_{2}^{2 -}$ should have a bond order of 3 (configuration $π_{u}^{2} π_{u}^{2} σ_{g}^{2}$ ). MOT configuration suggests that it contains one $σ$ and two $π$ -bonds
