WebWe are now able to explain the stereochemical results. Thermal and photochemical reactions yield different stereochemical results because reactions happen from different HOMOs. These different orbitals rotate by either a disrotatory or conrotatory process. … WebConrotatory is a antonym of disrotatory. In organic chemistry terms the difference between disrotatory and conrotatory is that disrotatory is describing an electrocyclic reaction in …

Exercise 2 There are 3 variables to consider in evaluating whether a sigmatropic rearrangement is allowed or … WebMar 23, 1999 · The transition state of the disrotatory pathway is about 11 kcal/mol lower in energy than that of the conrotatory pathway. The reaction path through cis−trans isomerization from cZc-hexa-1,3,5-triene to cyclohexa-1,3-diene was proposed. The conrotatory and the disrotatory reaction pathways were also characterized by the CiLC … WebThis problem has been solved!
