Description

Oxidation/Reduction Pre-lab! Part A. Oxidation of Isoborneol! 1) Typically a carbon atom gains bonds to more electronegative elements, and the most commonly is oxygen. Bleach and acetic acid equal / are oxidizing agents.! CH3

2) During the reduction of camphor, the reducing agent can approach the carbonyl face with a one carbon bridge or the face with a two carbon bridge. The two product stereoisomers are called borneol and isoborneol. The percentage of each of the isomeric alcohols in the mixture can be determined by gas chromatography analysis. IR analysis, unfortunately, does not allow this.! For percent yield of oxidation of isoborneol:! Mass of empty flask: 26.624 g! Mass of empty flask and camphor: 27.305 g! Melting point range of camphor: 169-172°C! Part B. Reduction of Camphor! 1) Decrease of camphor prompts the creation of borneol and isoborneol. These two are not interconvertable, and accordingly they are isomers. In both borneol and isoborneol the carbon bearing hydroxyl bunch is chiral, and there are other chiral focuses in every one of these atoms, make these liquor diastereomers. ! 2) The IR range is increasingly valuable to recognize borneol and isoborneol on the grounds that isoborneol give a more profound top than borneol which can be effectively distinguished. Yet, dissolving purpose of these two mixes is near one another subsequently it is hard to recognize.! For percent yield of the reduction of camphor:! Mass of empty beaker = 28.076 g! Mass of beaker# + product = 28.139 g! Melting point product = 204-206 CH
