H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight‚ I calculated

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

a special chemical compound—called CHEMIX—that is used extensively in high school chemistry classes. This compound must contain at least 20% sulfur‚ at least 30% iron oxide‚ and at least 30% but no more than 45% potassium. Tarmac’s marketing department has estimated that it will need at least 600 pounds of this compound to meet the expected demand during the coming school session. Tarmac can buy three compounds to mix together to produce CHEMIX. The makeup of these compounds is shown in the following
