We’re being asked to compare the H–H bond in H2 and in H2. For this, we need to determine the bond order for each species. The bond order tells us the strength and length of a bonda higher bond order means the bond is stronger and shorter.


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:
