I need to learn more about frontier orbitals and organic chemistry. Any references?
In electrophile aromatic substitution, how do you know the degree of hardness/softness to the attacking electrophile? And how do you decide the hardness/softness of the aromatic ring based on the already existing substituents?
I have a calculated HOMO and LUMO energies for a group of molecules. But sadly, I dont now how to use it to predict reactivity.
