What does the conservation of orbital symmetry say?
In that case, there will be __ to help stabilizethe TS. Without these bonding interactions int eh TS, the __ is much higher, and the concerted cyclic reaction cannot occur. Conservation of symmetryhas been used to develop "rules" to predict which __ are feasible and what products will result. These rules are often called the __.
the molecular orbitals of the reactants must flow smoothly into the MOs of the products without any drastic changes in symmetry
- bonding interactions
- pericyclic reactions
- Woodward-Hoffman rules
