So in this reaction, we're going to identify the homo and luma orbitals of a few reactions. Now, before we look at that, let's recall what homo and luma orbitals are. Now, recall that a lewis acidbased reaction is simply a reaction between the highest occupied molecular orbital known as the homo of one kind compound, and the lowest unoccupied molecular orbital of a second compound known as the lumo. So we basically have a pair of electrons, grams, another molecule, or compound. So let's look at the following reaction. So here we have an amine.
