Problem

What is the bond order for H2- (hint: use MO theory)?

A. 0.5 

B. 1 

C. 3 

D. 2 

E. 1.5

Solution

Calculate for the bond order of H2- using the MO theory and formula for bond order

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:

B.O. = 12e- in bonding MO - e- in antibonding MO
