Grignard reaction Abstract: In this laboratory‚ triphenylmethanol was synthesised from reacting benzophenone and bromobenzene using Grignard reaction. As the reaction was to set up to produce a Grignard reagent and then recrystallize it to obtain pure sample. The percentage yield obtained was 55% and its melting point was 161 co which is within the literature value 160-163 co. In addition to that the IR spectroscopy confirmed the molecule structure to be triphenylmethanol. Introduction: The Grignard

to be fixed‚ many more minorities would have jobs‚ putting them in a different environment more likely to succeed and stay out of trouble. A rich white man can commit the same crime as a poor black man‚ and the white man is almost guaranteed to not get charged remotely close to the charge that the black man would receive. With things like that happening ‚ it prolongs the reoccurrence of this happening‚ it starts to become viewed as normal‚ or the way it should be. White collar crimes are more spread

For a student such as myself‚ I have come to notice when one has a large amount of time to complete something they tend to wait till the last minute. I personally have taken the "get active" way of school. I began to join clubs and community activities to take up some of my time. By this I was left with less time to get my assignments complete‚ with that in mind I began to complete them as soon as my time opened up. with this open time it began to be that perfect amount of time to complete other

Get‚ Set‚ Style ! Long before the days of Lycra and spandex‚ ladies wore the height of fashion to cycle like Olympic record holder‚ Victoria Pendleton who wore a long-skirted white dress and tall bonnet trimmed with flowers. Women players wore corsets‚ painful and restricting‚ until 1925 when Suzanne Leglan wore a simple (and daring) one-piece cotton frock‚ without a petticoat or corset in sight. Stockings were discarded in 1929‚ and by 1939 tennis fashion became recognisably sportier and maybe

Experiment 15 & 16: Preparation of 1-bromobutane‚ an SN2 reaction Preparation of 2-chloro-2-methylbutane‚ an SN1 reaction 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

Biology coursework How does the temperature affect the rate of reaction? Introduction For our experiments‚ I was investigating what affects the rate of reaction. We used Hydrogen peroxide to test the rate of reaction‚ with the temperature of this being our variable that we changed. Hydrogen peroxide is a clear‚ colourless liquid which has various amounts of uses within the laboratory‚ industrial purposes and even in our households. It is mainly used for cleaning products and hair dye but is
