Remember, these bonds here are all known as Sigma bonds. While these bonds are known, the ones in red are known as pi bonds. So when the two p and two p interact, which are, by the way, higher in energy than the SP, they form the two p two p pi bonding molecular orbital. And the two p two pi antibonding molecular orbital. And once again, both electrons go into the lower in energy pi bonding molecular orbital. And no electrons go into the two p two pi antibonding molecular orbital.
