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 (15[1])antisymmetric with respect (15[1])to inversion. The Hückel method (15[1])calculates the energies of these constructs, (15[1])which are arranged in a polygon in the (*) Frost circle mnemonic for determining aromaticity. (-5[1])Kenichi Fukui pioneered predicting reactivity based on the frontier examples of these entities, which are the HOMO and LUMO. (-5[1])These entities can be approximated as linear combinations of their atomic counterparts. For 10 points, name these functions which describe the location of an electron in a molecule. ■END■ (10[2]0[4])
