Multistep Synthesis of Tetraphenylcyclopentadienone Author: Instructor: Date work performed: 10.18.2012--10.25.2012 Date work submitted: 11.01.2012 Abstract: The aim of this experiment was to perform a multistep synthesis to form tetraphenylcyclopentadienone. The first step of the reactions was to synthesize benzoin from the condensation of benzaldehyde. A yield of 28.91% benzoin was obtained. The MP of benzoin was 127O-130O C and the IR spectra displayed a carbonyl peak at 3415 cm-1

Legacies: Roman‚ Greeks‚ and Hebrews In the ancient days‚ when culture‚ as well as civilizations were developing‚ many things came to be known as options for later cultures. Civilizations had different ways of doing things and therefore each of their cultures differed considerably. The Romans‚ the Greeks and the Hebrews all presented different legacies to the world. The Romans actually gave a legacy from their political‚ and economic systems. From the political system they gave us two forms

Legacy Gardens: Segregation of the Student and the Public The presence of public space in a city is integral to the development of its citizens. Individuals can find themselves disconnected from their community when there are no areas in the city to intermingle. In “Brave New Neighborhoods‚” Margaret Kohn describes a public space as “a place that is owned by the government‚ accessible to everyone without restriction‚ and/or fosters communication and interaction” (11).

Lab #4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment‚ a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion‚ S2O82-‚ was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability‚ coupled with its strong oxidizing ability allowed for stabilization of
