Question

Draw the energy level diagram to show that N2 has triple bond, O2 has double bond, F2 has single bond ,Ne2 has no bond.

Answer 1

The energy level diagram for O2, F2 and Ne2.

 ✔ Fill the total electrons in respective orbitals for  O2, F2 and Ne2. Then calculate their bond order = (No of bonding electrons- No of non bonding electrons)/2. 

For O2 , Bond order = (10-6)/2= 2

For F2 , Bond order = (10-8)/2= 1

For Ne2 , Bond order = (10-10)/2= 0
