Note the appearance of the flame. 2) Shake 1cm3 (1 teat pipette full) of bromine water with 3 or 4 drops of cyclohexene in a test tube. Observe what happens. 3) Add 2 or 3 drops of potassium manganate (VII) solution to 2cm3 of bench sulphuric acid in a clean test tube. Add 3 or 4 drops of cyclohexene and shake. Observe what

reaction. In order to separate the cyclohexene product from the cyclohexanol starting component‚ previously learned lab techniques such as extractions and simple distillation were used. The formation of the product was verified by performing a Bromine test as well as an analysis using IR Spectroscopy. A percent yield of 8.33% was obtained. Introduction: In an elimination reaction‚ two substituents are removed from a molecule in either a one or two-step mechanism. There is a removal of a leaving

Relative Reactivity of Alkyl Halides Introduction Nucleophilic substitution of alkyl halides can proceed by two different mechanisms – the SN2 and the SN1. The purpose of the experiment was to identify the effects that the alkyl group and the halide-leaving group have on the rates of SN1 reactions‚ and the effect that the solvent has on the rates of SN1 and SN2 reactions. The SN1 mechanism is a two-step nucleophilic substitution‚ or unimolecular displacement. In the first step of the mechanism

"CHEMISTRY REVIEW" PROJECT PAGES This Project Page first appeared in the November 1996 issue of Chemistry Review‚ Volume 6‚ Number 2‚ Pages 14 and 15. Chemistry Review is published four times during the academic year by Philip Allan Updates and is a journal for post-16 students. It contains a variety of interesting and colourful articles aimed at 16-19 year-olds taking mainly AS and A2 courses in chemistry.

The reaction of 0.139 grams of trans-cinnamic acid‚ 0.8 mL of glacial acetic acid‚ and 1.0 mL of 1.0 M of Bromine in acetic acid was recrystallized to form a solid‚ clear‚ crystal- like product. The melting was taken from the recrystallized product to determine what had been obtained. The melting point was found to be 130.5°C-133.7°C. Concluding that the product formed from the addition of bromine was a mixture of the erythro-2‚ 3-dibromo-3-phenylpropanoic acid‚ which has a known melting point of 204°C
