The Wittig Reaction – Formal Report By: Alexander Davies Introduction Alkenes are important initial building blocks in many organic synthesis routes, as shown by Scheme 1.1 It is paramount, therefore, that we have the ability to synthesize alkenes from other readily available, cheap material. Scheme 1: Examples of one-step reactions from an alkene starting material. This illustrates the huge diversity of olefin products; and as such the need to be stereoselective in how one can synthesise said functionality within a molecule. […]
Introduction The purpose of this lab is as follows: 1) to learn about coordination compounds through the synthesis and analysis of a potassium ferrioxalate hydrate salt and 2) to use the techniques developed in previous labs to determine the empirical formula of the ferrioxalate salt. The ferrioxalate salt has the empirical formula Kx[Fey(C2O4)z]•nH2O. The values of x, y, z, and n are ascertained through determining the percentages of K, Fe, C2O42-, and H2O; converting these percentages to grams and then […]
The Dehydration of Alcohols By: Julia Trimble Introduction: Alcohols are organic compounds that derive from hydrocarbons that have replaced hydrogen with a hydroxyl group; the presence of a hydroxyl group is the primary signifier of this functional group.2 Given their structure, alcohols are capable of reacting with acids to create a more stable compound by cleaving the –OH group to make water.3 If a simple alcohol such as cyclohexanol were mixed with a strong acid like H2SO4 , the free H+ […]
Organometallic Chemistry and IR Spectroscopy – Synthesis of Molybdenum Carbonyl Complexes in a Microwave oven and Isomeric Phosphine Complexes By: Ansar Kapyatov Abstract [Mo(CO)4(NHC5H10)2] complex was prepared using a microwave synthesis method. Then Cis and Trans isomers of [Mo(CO)4(PPh3)2] were prepared and identified using IR spectroscopy and group theory analysis. Introduction This experiment is concerned with the study of some organometallic complexes, their thermodynamic stabilities and identification of their isomers. The actual preparation of our organometallic complexes deserves little attention seeing […]
Thermodynamics and Equilibrium By: Omish Samaroo Introduction The goal of this experiment is to determine the value of an equilibrium constant at different temperatures and use these data to calculate the enthalpy and entropy of reaction. The value of an equilibrium constant for a reaction varies, depending on the temperature. In endothermic reactions, the value of K increases as the temperature increases because heat can be thought of as a reactant. In exothermic reactions, and the value of K decreases […]
