The video tutorial explains how to use molecular orbital theory to analyze the bond order, bond strength, and magnetic properties of molecules like N2, N2 2-, and N2+. It begins with an introduction to molecular orbital theory and the problem statement. The tutorial then details the process of calculating the bond order of N2 using molecular orbital diagrams, followed by determining whether N2 is paramagnetic or diamagnetic. Finally, it compares the bond strength of N2, N2 2-, and N2+ based on their bond orders.
