Clement Organic Chemistry 2423‚ Section 304 25 October 2017 Lab 6: Natural Products I The main goal of this experiment was to employ isolation techniques to derive chemicals from two different natural sources and study their properties (Clement 91). The two natural sources used in this experiment were an orange (the peel contains limonene‚ which is a terpene) and a dichloromethane solution of clove oil (which contains eugenol‚ an acetogenin). To isolate the eugenol

EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase

have a group attached that is not easily named as a substituent‚ the benzene ring is often treated as a group to this substituent. The benzene ring attachment is called a phenyl group. The compound is named according to the rules for naming alkanes‚ alkenes and alkynes. Trivia: Phenyl comes from “phene”‚ a European term used during the 1800’s for benzene. Example: CH2 = CH – CH – CH3 3- Phenyl-1-butene Substituted benzene: position and name substituent/s (alphabetical) + benzene Note 1:

attraction between two molecules‚ pulling them together (also known as London dispersion forces). The magnitude pof Van der Waals force depends on the relative molecular mass‚ high mass produces a larger force. Boiling points of the alkanes data and alkenes data These very clearly illustrate the effect of increasing Van der Waals attractions as the relative molecular mass increases. The influence of branching in the alkanes can also illustrate the effect of different surface areas on the Van der Waala

The process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols. There are‚ however‚ a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. Ionic compounds If the compound is ionic‚ then the name of the cation (usually metal) comes first‚ followed by the ’compound’ name of the anion. To find the compound name of an anion‚ replace the end of the

The method used to separate the components was Thin Layer Chromatography (TLC) with silica adsorbent as the stationary phase and 0.5% glacial acetic as the mobile phase. In one plate‚ five known samples were used as the reference‚ that is: Aspirin; Caffeine; Ibuprofen; and Salicylamide. Aspirin and Salicylamide were the only samples that fluoresced
