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

Options

A. `Be_(2)` is not a stable molecule .
B. `He_(2)` is not stable of `N_(2)` is maximum amongst the homonuclear diatomic molecules belonging to the second period .
C. Bond strength of `N_(2)` is maximum amongst the homonuclear diatomic molecules belonging to the second period.
D. The order of energies of molecular orbitals in `N_(2)` molecule is ` sigma 2s lt sigma^(***) 2s lt sigma2p_(z) lt (pi 2p_(x) = pi 2p_(y)) lt (pi^(***) 2p_(x) = pi^(***) 2p_(y)) lt sigma^(***) 2p_(z)`

Answer

D

Explanation

The correct order of energies of molecular orbitals in `N_(2)` molecules is
`sigma 2s lt sigma^(**) 2s lt (pi 2p_(x) = pi 2p_(y)) lt sigma2 p_(z) lt (pi^(**) 2p_(x) = pi^(**)2p_(y)) lt sigma^(**) 2p_(z)`
