FREE Expert Solution

Construct the molecular orbital diagram of NO+ and calculate for the bond order and determine if its paramagnetic or diamagnetic


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

Step 2: Draw the molecular orbital diagram.

Step 3: Determine if there's an unpaired MO (paramagnetic or diamagnetic)

Step 4: Calculate the bond order of the molecule/ion. Recall that the formula for bond order is:


Bond order = 12# e- in bonding MO - # e- in anti-bonding MO
