Conservation of molecular orbital symmetry
WebMolecular orbital symmetry conservation constrains all molecular systems to specific paths of transformation. Symmetry conservation principles have proven to be powerful … WebThe Woodward-Hoffmann rules are based on the principles of molecular orbital theory and the conservation of orbital symmetry. According to these rules, the outcome of a pericyclic reaction depends on the symmetry of the molecular orbitals involved in the reaction and the number of electrons being transferred.
