The first day the clove oil was removed from the ground cloves into an aqueous solution then removed from the water using DCM. The sample was left in a sealed container for one week and then isolated by drying the sample and removing the DCM. After the clove oil was isolated it was analyzed using IR spectroscopy.

The Basics of NMR Chapter 1 INTRODUCTION [pic] NMR Spectroscopy Units Review [pic] NMR Nuclear magnetic resonance‚ or NMR as it is abbreviated by scientists‚ is a phenomenon which occurs when the nuclei of certain atoms are immersed in a static magnetic field and exposed to a second oscillating magnetic field. Some nuclei experience this phenomenon‚ and others do not‚ dependent upon whether they possess a property called spin. You will learn about spin

concentrated sulfuric acid as a catalyst. The product was washed with sodium hydrogen carbonate‚ as well as with water‚ then dried with anhydrous sodium sulfate. The product was then distilled using a Hickman still and characterized using infrared spectroscopy. The percent yield of isopentyl acetate was 61.52%. This may have been low due to not all of the condensed product being removed from the Hickman still‚ some product being lost during transfer of the product from the reaction tube into the Hickman

Objective: To determine the concentration and equilibrium constant for a reaction of colored product using absorption spectroscopy‚ to create a calibration curve for determining equilibrium concentrations by applying Beer’s law and to force the completion of a reaction by applying Le Châtelier’s principle. Procedure: A diluted solution was made from the stock of 0.0025 M Fe(NO3)3 by diluting 4.0 mL to exactly 100.00 mL‚ using serological pipet and volumetric flask. The concentration of the diluted

Alkene Synthesis from Alcohol: Preparation of Cyclohexene From Cyclohexanol 5/29/14 Abstract: A 42.89% yield cyclohexene was successfully synthesized from 10.0 mL cyclohexanol by unimolecular elimination (E1) through the dehydration of cyclohexanol and confirmed via a bromine test and the IR spectra. Introduction: Alkenes are hydrocarbons that have carbon–carbon double bonds and are one of the many functional groups in organic molecules. Alkenes are sp2 hybridized
