Introduction The bromination of cyclohexene is a classical organic chemistry experiment designed to elucidate the addition of bromine to alkenes. This reaction entails the addition of an electrophilic electron promoter across a carbon-carbon double bond, and the formation of vicinal dibromide. Scheme 1 indicates the net reaction. During the process of the experiment, different analytic methods were implemented to distinguish the reaction product, such as gas chromatography (GC), thin layer chromatography (TLC), and infrared (IR) spectroscopy.

The course of bromination of cyclohexene was studied and characterized through spectrometry techniques (IR), thin-layer chromatography (TLC) and GC-MS. The goal had been to be able to synthesize 1,2-dibromocyclohexane, but the presence of many different peaks in the GC and spots on the TLC plate, resulted in the straightforward conclusion that most likely by products or the incomplete reaction had been formed.The results of the …show more content…
The regional alcohol next in order, 1-bromocyclohexane, also satisfies the data of GC-MS and confirms the existence of partially brominated alkyl compound. This suggests that the adaption is cyclohexene, a likely unused substance. Nonetheless, the absence of an Rf value restricts quantitative interpretation; however, it is possible to deduce that one of the poles experienced the reaction as well as the kinetics of the
