1.	Assuming 2s - 2p mixing is not operative , the paramagnetic species among the following is
Answer» `Be_(2)` `B_(2)` `C_(2)` `N_(2)` Solution :If `2S - 2p ` MIXING is not operative , then molecular orbitals may be ARRANGED in ORDER of energy as follows : `sigma (1s), sigma^() (1s), sigma(2s), sigma^() (2s), sigma(2p_(z)), PI(2p_(x))` `= (2p_(y)), pi^() (2p_(x)) = pi^() (2p_(y)), sigma^(**) (2p_(z))` Applying this configuration , `Be_(2), B_(2) and N_(2)`will be diamgnetic but `C_(2)` will be paramagnetic .
