its mechanism as nucleophilic substitution reaction. The alcohol which contains a hydroxyl group (OH-) has a partial negative charge compared to the alkyl group bound to it which is Isopropyl in this lab. The reason is that oxygen has higher electronegativity compared to carbon. So‚ there is more attraction to the lone pair electrons around oxygen which makes the hydroxyl group partially negative. Analyzing the structure of the glacial acetic acid‚ we notice that the hydroxyl group and the oxygen

Jacobsen’s Method of Epoxidation of an Alkene | | Abstract Various types of reactions were completed to first create and then use Jacobsen’s catalyst in the asymmetric epoxidation of an unknown alkene with bleach in the laboratory. The chiral epoxide synthesized was then characterized with GC/MS and NMR. With this information the unknown alkene was able to be identified as 4-chlorostyrene. Introduction Organisms have evolved with mechanisms that use specific enantiomers of molecules
