So we create confirmations or confirmations of ethane. So we could have an eclipse confirm, and we could have a staggered confirm. Now, notice what happens in our double bond molecule. So here we have the following ethylene lean. So, notice that these ch bonds on Ethylene lean are on the same plane. And these two orbitals here, this Pi orbital is created by an overlap of two P orbitals down perpendicular to either of BCH bonds.
