Physical properties of organic compound Low boiling point group: alkane‚ alkene‚ alkyne and ether Boiling point is the exact temperature that the state of compound change from liquid to gas‚ which need to break the intermolecular forces. The stronger the intermolecular forces‚ the higher the boiling point. Since straight chain alkane‚ alkene and alkyne only experience dispersion forces‚ the compound with more carbons have higher boiling point as more carbons contribute more forces. Branched

Identifying Organic Compounds Joe Harris 11/12/07 1. Background Organic compounds are‚ by definition‚ any chemical compound containing carbon. These compounds include carbohydrates‚ polysaccharides‚ lipids‚ proteins‚ and nucleic acids. Each one of these compounds has a different purpose. Carbohydrates give energy to cells when consumed. Lipids are basically the

Chemical Reaction of copper compounds Introduction: In this experiment‚ the objective was to conduct a series of chemical reactions that contain copper or copper compounds. That is to say that the products of each chemical reaction were used in the next reaction. The process starts with a solid copper wire dissolved in nitric acid and the end product is copper powder. The product which was used from the previous reaction is the limiting. In the initial step‚ the solid copper is the limiting reactant

WHAT IS PHARMACOGNOSY? Pharmacognosy is the study of drugs of natural origin. The term comes from two Greek words: "pharmakon" meaning drug or medicine‚ and "gnosis" meaning knowledge. The American Society of Pharmacognosy defines pharmacognosy as "the study of the physical‚ chemical‚ biochemical and biological properties of drugs‚ drug substances or potential drugs or drug substances of natural origin as well as the search for new drugs from natural sources".

The Pareto principle (also known as the 80–20 rule‚ the law of the vital few‚ and the principle of factor sparsity) states that‚ for many events‚ roughly 80% of the effects come from 20% of the causes.[1][2] Business-management consultant Joseph M. Juran suggested the principle and named it after Italian economist Vilfredo Pareto‚ who observed in 1906 that 80% of the land in Italy was owned by 20% of the population; he developed the principle by observing that 20% of the pea pods in his garden contained
