So let's begin by adding or by combining the positive two p and the positive to P. We get the following orientation. Now notice in this orientation we have the positive interacting in a bonding way with the positive and so that forms a bond. And here we have an anti bonding interaction because the negative of this two p orbital interacts with the positive section of this two p orbital. So we have bonding and antibounding. So let's look at the negative. Or simply we're combining two p positive and two p negative.
