The subject of phytochemistry or plant chemistry has been developed in recent years as a distinct discipline‚ somewhere in between plant biochemistry and natural product organic chemistry and is closely related to both. It is concerned and linked with the enormous variety of organic substances that are synthesized‚ elaborated and accumulated by wide variety of plants and deals with the chemical structures and

PURPOSE To introduce two physical properties‚ the boiling point and the melting point‚ that organic chemists use to identify organic molecules. BACKGROUND/INTRODUCTION Organic chemistry is the branch of chemistry that deals with carbon containing molecules. Carbon can bond to other atoms forming multiple chains and rings‚ thus creating an unlimited number of organic compounds to exist. Each organic compound has many chemical and physical properties associated with its structure. In this experiment

of the melting point is very important technique in many areas of chemistry especially‚ in organic chemistry area because the melting point is really significant in order to identify the purity and the identity of a substance. Measuring the melting point is a fast and cost-effective technique which remains a strong link to the vast pre-instrumental chemistry literature‚ so the technique is still used for measuring purity of organic and pharmaceutical compounds. For that reason‚ determination of the

The Synthesis of Alkenes: The Dehydration of Cyclohexanol Adam Ohnmacht CHEM 0330 Scott Caplan 10/30/12 Abstract: In Organic Chemistry‚ many different methods are used to synthesize organic compounds from various components. In this lab‚ cyclohexanol was dehydrated to cyclohexene through an elimination 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.

dehydration of 2-butanol yielded 4.6% 1-butene‚ 67.3% trans-2-butene‚ and 28.1% cis-2-butene‚ and a dehydrohalogenation of 2-bromobutane yielded 19.1% 1-butene‚ 69.9% trans-2-butene‚ and 11.0% cis-2-butene. Backround: Gas Chromatography separates organic samples much in the same way as column chromatography. The only differences are that it uses a moving gas phase and a stationary liquid phase‚ and that the temperature of the gas system can be controlled. In a gas chromatograph the sample is shot
