SOLVED:We calculated the π-electron energy of a trimethylenemethane molecule in Problem 10-31. Derive the symmetry orbitals for the πorbitals by applying the generating operator, Equation 12.32, to the atomic 2 p2 orbital on each carbon atom. Identify the irreducible representation to which each resulting symmetry orbital belongs. Derive the Hückel secular determinant corresponding to these symmetry orbitals and compare it to the one that you obtained in Problem 10-31. Compare the π-electron ene

Methane - an exceptionally powerful greenhouse gas - usually lasts about 12 years in the atmosphere, compared to centuries with carbon dioxide. But its levels today are nearly three times higher than in the pre-industrial era, begging the question: are we overlooking methane to reach our climate goals?
