Problem

What is the bond order of Be2 ?

Solution

We’re being asked to determine the bond order of Be2-. For this, we need to do the following steps:


Step 1: Calculate the total number of valence electrons present.

Step 2: Draw the molecular orbital diagram.

Step 3: Calculate the bond order of the molecule/ion. Recall that the formula for bond order is:


Bond Order = 12[# of e- in bonding MO - # of e- in antibonding MO]
