Dihydroxylation of Cyclohexene Essay Preview: Dihydroxylation of Cyclohexene Report this essay Dihydroxylation of Cyclohexene Abstract This was a microscale experiment in which cyclohexane-1,2-diol was synthesized by dihydroxylation of cyclohexene. Oxone, a persulfate mix that reacts with acetone to produce dimethydioxirane, reacts with cyclohexene to form cyclohexane-1,2-diol. Through a thin layer chromatography (TLC) analysis, it was.
The Lowry and Brønsted TheoryThe Lowry and Brønsted theory suggest that defining acids as chemicals that donate a proton (H +) in a chemical reaction and bases as chemicals that accept a proton. This definition is slightly more useful than Arrheniuss definition. Gilbert Lewis definition of acids and bases was different. Lewis suggested that an.
