Pairs of these entities with comparable symmetry move energy from the lower to the higher energy counterpart via mixing. These entities are designated ungerade (“OON-gur-ah-duh”) if they are antisymmetric with respect to inversion. The Hückel method calculates (-5[1])the energies (-5[1])of these constructs, which are arranged in a polygon in the (*) Frost circle mnemonic for determining aromaticity. Kenichi Fukui pioneered predicting reactivity based on the frontier examples of these (10[1])entities, which are the HOMO and LUMO. These entities can be approximated as linear combinations (10[1])of their atomic counterparts. For 10 points, name these functions which describe the location of an electron in a molecule. ■END■ (10[1]0[1])
