So all of these guys are perpendicular to one another. So now let's look at the energy diagram for all these interactions. So the One s interacts with the SP to form the one s SP? Molecular orbital. In other words, notice that the one s is lower in energy than the SP because the one s has more s character than the SP does. And so when they interact, they form two types of molecular orbitals bonding and the antibonding molecular orbitals.
