WebJan 31, 2024 · Comparing the Hückel and extended Hückel methods. I'm very confused about the differences between these methods. From my textbook, it states that the Hückel method only takes into account the π bonding interactions, while the extended Hückel method takes into account all the valence electrons.

In Hückel theory we are only interested in π systems, where $\mathrm p_z$ orbitals overlap. One of the approximations in Hückel theory is that the overlapping $\mathrm p_z$ orbitals are orthonormal: If orbital overlap leads to bond formation, how can the overlap integrals, between $\mathrm p_z$ orbitals ...
