FREE Expert Solution

Bond order =12[(# of e- in bonding MO)-(# of e- in antibonding MO)]



For B2:

Step 1: The total number of valence electrons present in B2 is:


            Group             Valence Electrons

B         3A                   2 × 3 e6 e

Total:  6 valence e


Step 2: The molecular orbital diagram for B2 is:
