🤓 Based on our data, we think this question is relevant for Professor Altomare's class at UCF.

Solution: Explain the following.The O22+ ion has a stronger O-O bond than O2 itself.

Problem

Explain the following.

The O22+ ion has a stronger O-O bond than O2 itself.

Solution

We’re being asked why O22+ ion has a stronger O-O bond than O2 itself.

For this, we need to determine the bond order for each species. 

The bond order tells us the stability of a bonda higher bond order means the bond is more stable and stronger.


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]
