🤓 Based on our data, we think this question is relevant for Professor Castaneda's class at UMICH.
We’re being asked to rank the given species in order of increasing bond length and increasing bond energy.
Recall that the bond order tells us the strength and length of a bond: a higher bond order means the bond is stronger and shorter.
higher bond order → higher bond strength → shorter bond length → higher bond energy
We can calculate for the bond order using:
bonding MOs → without an asterisk (e.g., σ1s)
antibonding MOs → those with an asterisk (e.g., σ1s*).
To do so, we need to look at the molecular orbital (MO) diagram of each molecule. Recall that we have two types of MO diagrams:
Place the species B2+, B2, and B2- in order of increasing bond length and increasing bond energy.
