Epoxidation Reactions Lab Report 2 Abstract An oxygen atom is transferred from a peroxy acid to the carbon=carbon double bond thus forming an epoxide. Scheme 1. Oxone Epoxidation. Scheme 2. mCPBA Epoxidation. The percent yield for the Oxone epoxidation reaction was 65% yield and the mCPBA epoxidation reaction was 70% yield. Oxone is the greener alternative because using mCPBA is twice as expensive as Oxone and leaves behind the epoxide plus m-chlorobenzoic acid while Oxone creates non-toxic

Qualitative Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds‚ one solid and one liquid‚ from an ethereal solution using the techniques of chemically active extraction‚ vacuum filtration‚ simple distillation‚ and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges‚ and analyzing IR and proton/carbon NMR spectrums It was determined

hydride addition is that product is entirely a racemic mixture (McMurry 696). After the initial reaction the product was isolated using a series of vacuum filtrations‚ ether extractions‚ and rotorary evaporations‚ before being analyzed via proton NMR spectroscopy. Results and Discussion: The table listed below as Table 1 lists the starting amounts of each of the chemicals present in the reaction flask‚ along with their formula mass.

Abstract Chemically active extraction was used to separate two unknown compounds from each other and to determine what compound class each compound belongs. The solid unknown was purified by recrystallization and its melting point range was determined to be 109-111°C. The liquid unknown was purified by simple distillation and its boiling point was determined to be 95°C. An IR spectrum was collected for each of the purified compounds; the solid was determined to be 3-toluic acid and the liquid was

parents forced him to leave his hometown and move to Rome‚ once there he began his studies into the humanities and philosophy. Angelo became a great success in his work and made many large leaps in the field of Astrophysics‚ he pioneered stellar spectroscopy (the light spectrum of stars in the solar system) and he also made the first systematic survey of the night sky. He also revolutionised humanities understanding of the sun including sun-spots solar prominences and metals in the sun. His expertise

Title: Introduction to Spectrophotometric Analysis Introduction: Spectrophotometric Analysis which is one of the most common and valuable analysis techniques used to study the interaction of electromagnetic radiation with chemical compounds (Stewart & Ebel‚ 2000). By using spectrophotometric analysis or spectrophotometry‚ one can determine the identity in terms of structure and species of a biomolecule as well as establish the concentration of a certain biomolecule (Stewart & Ebel‚ 2000).

Post-Lab Report for Experiment 2: Cooperative Identification of an organic Solid October 6‚ 2013 Introduction: This experiment was focused on the cooperative identification of organic compound by its chemical properties such as: slow melting point‚ mixed melting point‚ Rf values in TLC experiment‚ IR spectrum analysis‚ and H NMR spectra. Such data can provide the the identity of functional groups and the identity of the compound itself. In this experiment

Introduction The purpose to of this experiment is to carry out the alkylation of sodium saccharin with iodo-ethane and analyze the product mixture to determine the structure of the major product. Sodium saccharin is made from the base catalyzed de protonation of saccharin. This nucleophilic reaction is special because the nucleophilic atom can be oxygen or nitrogen and the leaving group is iodide ion. The solvent used in this reaction is very important for determining the rate of nucleophilic
