Caroline Guidry Dr. Beverly A. 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

layer contains sodium hydroxide and water‚ whereas the organic layer contains the dichloromethane‚ aspirin‚ and the unknown. If the HCl has nothing to react with in the aqueous layer following mixing (i.e.‚ sodium acetylsalicylate)‚ then little to no solid aspirin will be produced. Furthermore‚ more unknown would be produced than expected because aspirin would precipitate with the unknown during distillation. (c) Mistakenly extracting the dichloromethane solution with 5% HCl rather than 5% NaHCO3 would

Copper Cycle Summary During the copper cycle lab‚ my partners and I performed a series of reactions on copper powder and observed the changes it underwent. For the first step‚ we mixed nitric acid and copper powder‚ and noticed that a yellowish brown gas emerged‚ along with effervescence. The red solid disappeared and became a blue liquid. We know that we produced copper nitrate‚ nitrate gas‚ and water because the only two blue solutions in “A New Language” are copper sulfate and copper nitrate

Explore the relationship between reactants producing a product and product breaking apart to its original reactant. Watch as both reactant and product reach a state of balance. No pressure greater than one another. Collision model provides characteristics of chemical reaction. Molecules must collide in order to react; and Characteristics such as higher concentrations‚ high temperature‚ etc. plays the role of increasing the speed of reaction or having more collisions. Scientists use collision model

CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings
