Remember, this electron is found at the same time in this region, as well as in this region. So that means there will be interaction between these two lobes here. And so this is known as our Pi bond, and this is known as our Sigma Bond. And once again, this pi bond will be higher in energy than this Sigma Bond. Another way of drawing this a more simpler way is simply with two bonds here, two dashes here. Now, notice that this is a Sigma bond, and the top one is a Pi bond.
