1.	Which of the following statements is not correct form the view point of molecular orbital theory ?
Answer» `Be_(2)` is not a stable molecule `He_(2)`is not stable but `He_(2) ^(+)`is EXPECTED to exist Bond strength of `N_(2)`is maximum amongst to homonuclear DIATOMIC molecular belonging to the SECOND PERIOD The order of energies of molecular orbitals in`N_(2)` molecule is ` sigma 2sltsigma^() 2s lt sigma 2p_(z) lt (pi 2p_(x) = pi 2p_(y))` `lt (pi^() 2p_(x) = pi^() 2p_(y)) lt sigma^() 2p_(z)` Solution :The correct order of energies of molecular orbitals in `N_(2)`molecule is `sigma _(2s) lt sigma_(2s)^() lt (pi_(2_(p_(x))) = pi_(2_(p_(y)))) lt sigma _(2_(p_(z)))lt (pi_(2_(p_(x)))^() = pi_(2_(p_(y)))^()) lt sigma_(2_(p_(z)))^()`
