UNIVERSITY OF THE GAMBIA LECTURE NOTES COURSE: PRINCIPLES OF CHEMISTRY II (ORGANIC CHEMISTRY) CODE: CHM 161 2ND SEMESTER SESSION: 2012/2013 LECTURER: ANTHONY F. ADJIVON UNIT 1 INTRODUCTION Organic chemistry started as the chemistry of life‚ when that was thought to be different from the chemistry in the laboratory. Then it became the chemistry of carbon compounds‚ especially those found in coal. Now it is both. It is the chemistry of the compounds of carbon along with other elements

CHAPTER 1 INTRODUCTION 1.1 PRELIMINERIES Due to highly development of chemical and biochemical industries‚ acetic acid has largely produced to fulfil the needs of world demand in production of daily used products and for pharmaceutical needs. Therefore‚ this study is carried out to introduce the production of acetic acid using biological pathways which includes the used of microorganisms. In this chapter will briefly explained on the knowledge about acetic acid and the microorganism

“Fmoc chemistry”. The first part of experiment was the synthesis of L-phenylalanine methyl ester hydrochloride. The methyl ester can be synthesised by reaction of thionyl chloride‚ SOCl2 and dry methanol with L-phenylalanine under reflux condition. The peptide bond was formed later in the experiment‚ where HBTU‚ DiPEA and a solution of Fmoc-Gly-OH in DMF were added to a solution of L-phenylalanine methyl ester hydrochloride in DMF. The product formed was the protected dipeptide‚ Fmoc-Gly-Phe-OMe. The

Determination of the concentration of ethanoic acid in commercial vinegar Introduction: The aim of the experiment was to determine the molarity of ethanoic acid in table vinegar by titrating a sample with alkali sodium hydroxide (NaOH) with a known concentration of 0.1molL-1. The equation of the reaction between ethanoic acid and sodium hydroxide is as follows: CH3COOH + NaOH CH3COONa + H2O When the titrations end point is determined and volumes of reactants are measured the concentration
