Discussion & Error Analysis: By examining the unknown alcohol’s H NMR spectra‚ it can be deduced that the alcohol is 1-(3-methoxyphenyl)ethanol. There are three peaks that have a shift of ~7.0-7.5‚ one with integration values of 1‚ 2‚ and 1.This shows that the alcohol is a meta-substituted benzene ring. The singlet peak with a chemical shift of~ 4.7 ppm with an integration of 1 is from the hydrogen on the OH group. The peak at ~ 1.7 ppm corresponds to the hydrogen of the carbon that is attached

November 15‚ 2007 Synthesis of 1-Bromobutane Introduction: The purpose of this experiment is to synthesize 1-bromobutane from 1-butanol and sodium bromide. In order for this reaction to reach completion there are four major operations that need to be performed. The four major operations include refluxing‚ simple distillation‚ separation‚ and drying. To begin‚ in order for the compounds to react they will be dissolved in water and sulfuric acid will be added. The addition of sulfuric acid will

Utilization of Camias in the production of “Bilimbi Juice” Camias Averrhoa bilimbi (commonly known as bilimbi‚ cucumber tree‚ or tree sorrel) is a fruit-bearing tree of the genus Averrhoa‚ family Oxalidaceae. It is a close relative of carambola tree. It is very common in Thailand‚ Malaya and Singapore. The bilimbi is closely allied to the carambola but quite different in appearance‚ manner of fruiting‚ flavor and uses. The only strictly English names are "cucumber
