Text solutionVerified

(a) In Hund's rule of maximum multiplicity, if two or more orbitals of equal energy are available, electrons will occupy them singly before filling them in pairs.

B_{2} (10) = σ_{1 s^{2}} σ_{1 s^{2}}^{*} σ_{2 s^{2}} σ_{2 s^{2}}^{*} π_{2 p_{x}^{2}}

Number of bonding electrons

= 6

Number of Antibonding electrons

= 4

Bond order

= \frac{(Number of bonding electrons - Number of antibonding electrons)}{2}

Bond order

= \frac{6 - 4}{2} = 1

Since there are no unpaired electrons, it is diamagnetic in nature.
