Under thermal conditions,a [1,5] carbon migration that occurs suprafacially must also occur with inversion of configuration at the migrating carbon Under thermal conditions,a carbon migration that occurs suprafacially must occur with inversion no matter the system's symmetry.

As you might suspect, B-carotene, C,Hw precursor to vitamin A, was first isolated from carrots. Dilute solutions of B-carotene are yellow, hence its use as a food coloring. In plants, it is almost always present in combination with chlorophyll to assist in the harvesting of the energy of sunlight and to protect the plant against reactive species produced in photo- synthesis. As tree leaves die in the fall, the green of their chlorophyll molecules is replaced by the yellows and reds of carotene and carotene-related molecules. Compare the carbon skeletons of B-carotene and lycopene. What are the similarities? What are the differences? H3C. H3C CH3 CH3 CH3 H,C CH3 CH3 CH3 B-Carotene
