$B_2$

Vedclass · Answer

(B) According to Molecular Orbital Theory $(M.O.T.)$,the electronic configuration of $B_2$ is $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \pi 2p_x^1, \pi 2p_y^1$.In $B_2$,the bond order is $1$,and the bond is formed by the overlap of $2p$ orbitals,which is a $\pi$-bond.Since $B_2$ has two unpaired electrons in the $\pi 2p$ orbitals,it is paramagnetic.$C_2$ has a bond order of $2$ (both $\pi$-bonds) but is diamagnetic.${O_2}^-$ has both $\sigma$ and $\pi$ bonds and is paramagnetic.$N_2$ has one $\sigma$ and two $\pi$ bonds and is diamagnetic.Therefore,$B_2$ is the correct species.

List-$I$	List-$II$
$A. Li_2$	$i. 3$
$B. N_2$	$ii. 1.5$
$C. Be_2$	$iii. 1.0$
$D. O_2$	$iv. 0$
	$v. 2$

Which of the following species contains only $\pi$-bonds but exhibits paramagnetic nature?
