Which of the following statement is not correct from the view point of molecular orbital theory?

(i) Be2 is not a stable molecule.

(ii) He2 is not stable but He2 + is expected to exist.

(iii) Bond strength of N2 is maximum amongst the homonuclear diatomic molecules belonging to the second period.

(iv) The order of energies of molecular orbitals in N2 molecule is

σ2s < σ* 2s < σ2p_z < (π2p_x = π2p_y ) < (π*2p_x = π* 2p_y) < σ* 2p_z

He₂ has zero bond order hence it does not exist.

The three fundamental laws of chemistry are - Law of Definite Proportions, Law of Conservation of Mass, and Law of Multiple Proportions.

The three types of chemical bonds are - ionic, metallic and covalent bonds. When the electrons transfer between the atoms, they form the Ionic bonds by producing charged ions that are attracted to each other. When atoms share electrons, covalent bonds are created. When metal atoms share a sea of del
