Question
Valence isomers are constitutional isomers that interconvert via these reactions. For 10 points each:
[10m] Name this type of reaction that may be analyzed using the Möbius–Hückel treatment. Classes of these reactions include dyotropic reactions and group transfer reactions.
ANSWER: pericyclic reactions [prompt on electrocyclic reactions or electrocyclizations, cycloadditions, cycloeliminations, sigmatropic reactions, ene reactions, or cheletropic reactions by asking “what is the general class of reactions?”]
[10e] Pericyclic reactions are sometimes contrasted with a class of reactions described by this word. This is the VSEPR (“vesper”) geometry of triiodide (“tri-iodide”) and carbon dioxide.
ANSWER: linear
[10h] Linear reactions, pericyclic reactions, and this third class of reactions comprise the primary concerted reaction topologies. The transition states of these reactions are characterized by possessing two rings.
ANSWER: coarctate reactions [accept pseudocoarctate reactions]
