Now, when we combine the two positive orbitals, we get the following figure. When we combine the positive one S orbital and the negative one two p orbital, we get the following interaction. To get the negative two p, we simply switch it or flip it. So here we have our two interactions. So let's look at this guy. So, our positive will want to interact in a bonding way with the positive two p. So positive one s wants to interact with the positive sign of the two P orbital.
