Question

Professor PC Thomas Classes · Answer

(c) : $\mathrm{B}_{2}$ molecule has the following electronic configuration:\ $\left(\sigma 1 s^{2}ight)\left(\sigma * 1 s^{2}ight)\left(\sigma 2 s^{2}ight)\left(\sigma * 2 s^{2}ight)\left(\pi 2 p_{x}^{1}=\pi 2 p_{y}^{1}ight)$\ $	herefore \quad$ It is paramagnetic.\
