Answer / slyos
If the process involves 4n electrons and is realised in a
conrotatory maner, then it is thermally favored.
Therefore the basic rule: 4n Thermic Conroratory
a 4n+2 electrons process will then necessarly be
Photochemically favored in a conrotatory way or thermically
favored in a disrotatory way.
