1.	Which of the following statements is not correct from the view point of molecular orbital ?
Answer» ` Be_2` is not a stable molecule `He_2` is not stable but `He^(+)` is expected to exist Bond strength of `N_2` is MAXIMUM AMONGEST the homonuclear diatomic molecules The order of energies of molecular orbitals in `F_2` molecule is `E (sigma 2s) lt E ( sigma^( ) 2s ) LTE ( pi 2p_x ) ` `=E(poi 2p_y ) ltE ( sigma 2p_z ) lt E ( pi^() 2p_x)` `=E ( pi^() 2p_y)lt E ( sigma^( ) 2p_z)` Answer :D
