Experiment Date: 3/12/2012 Photochemistry: Photoreduction of benzophenone and rearrangement to benzpinacolone Abstract: In this experiment Benzpinacolone was synthesized in a process that contained two steps. First the photoreduction of benzophenone in 2-propanol‚ which was done by placing the flask under sunlightfor the absorption of the UV rays to carry out the reaction. Then the second part was the dehydration of benzpinacol to benzpinacolone‚ where the benzpinacol product was converted

should happen is that the nitric acid and ammonia react with the aromatic ring and gives a coloured salt compound. When Nitric acid is heated with a protein like tyrosine it gives off a yellow colour ‚or tryptophan and orange colour this is down to nitration. This is why this test is used for the presence of an activated benzene ring. The “(4) Test for sulphur”this

Introduction Carboxylic acids is an organic compound that contains a carboxylic group(-COOH). Its general formula is R-C=OOH with R referring to the rest of the molecule such as H and C. They are directly attached to a carbonyl group and the interaction between them affects the reactions of each. The polarity of the O-H bond

The Purity and Purification of Solids Melting Points CH-337 Abstract: The purpose of this experiment was to find the eutectic point for the mixture of naphthalene and biphenyl. This was done by measuring the melting point of both pure substances and five mixtures of different ratios. The purpose of the second section was to identify an unknown sample by measuring its melting point and mixing it with two known substances and comparing them. The results suggest that the eutectic point is closest
