Assertion : $B_{2}$ molecule is diamagnetic. Reason : The highest occupied molecular orbital is of $σ$ type.

Options:

Answer:

Solution:

In $B_{2}$ , total number of electrons $= 10$ $B_{2} \to σ (1 s)^{2} σ^{*} (1 s^{2}) σ (2 s)^{2} σ^{*} (2 s)^{2} σ (2 p_{x})^{1} π (2 p_{y})^{1}$ Presence of unpaired electron shows the paramagnetic nature. The highest occupied molecular orbital is of $π$ -type.
