How many pi bonds in beta carotene
WebButadiene has two pi bonds (double bonds). These are conjugated structures, meaning that they have two bonding and two anti-bonding orbitals each. The more nodes there are, the more unstable the compound becomes. Therefore, arranged in energy order, butadiene can be divided into the following orbitals. WebBeta-carotene (BC) degradation was studied by liquid chromatography coupled to a quadrupole time of flight mass spectrometer. Throughout/After 21 days of dark storage, 56 nonvolatile degradants were chromatographically separated from pure BC crystal and their molecular formulas were identified. Thei …
