Q. Assuming $2s-2p$ mixing is NOT operative, the paramagnetic species among the following is

Chemical Bonding and Molecular Structure

Solution:

as it has two unpaired electrons
$Be_2 = \sigma 1s^2 \sigma^* 1s^2, \sigma2s^2 \sigma^* 2s^2$
$B_2 = \sigma 1s^2 \sigma^* 1s^2, \sigma2s^2 \sigma^* 2s^2 \sigma 2p_z^2$
$C_2 = \sigma 1s^2 \sigma^* 1s^2, \sigma2s^2 \sigma^* 2s^2 \sigma 2p_z^2 \pi 2p_x^1 \pi 2p_y^1$
$N_2 = \sigma 1s^2 \sigma^* 1s^2, \sigma2s^2 \sigma^* 2s^2 \sigma 2p_z^2 \pi 2p_x^2 \pi 2p_y^2$
