Instructions and help about 1 "Tunnelling Dynamics Of Cyclobutadiene" M

so we just finished looking at benzene now which is an aromatic compound now let's look at the molecular orbitals for cyclobutadiene which is an anti-aromatic compound now we can do the same process that we did for benzene which is we're going to draw this molecule with a vertex pointing in the downward direction here just like this and we'll just add in some double bonds in there and then when we draw the molecular orbital diagram we'll have one bond down here two right there and then one up here and what this is going to do is we've got two two electrons here two there so that's four total so i'm going to start filling these orbitals when i get up here i'm going to notice i've got unpaired electrons here that's not stable we generally like to have electrons paired up when they're in an organic molecule and so that's uh that's kind of a flag right there we've got unpaired electrons and furthermore these are directly in between what would be a bonding orbital right here and an antibond
