How to determine the bond order of a molecule ? Please illustrate the electronic configuration of molecular orbital also.

I suggest you that you should remeber the bond orders of all the elements starting from at. no. 1 to 10

.i.e hydrogen to helium.

Steps to find B.O

1) First write the electronic configuration of the molecule according to ''MOT''

2) Now, count the no. of electrons in B.MO AND ABMO then put in the below formulae.

3) B.O = (electronsin B.MO - electrons in A.BMO)/2
