Lab 5 Oxidation of an alcohol CHM2123 Introduction: Oxidation is a key reaction in organic chemistry. Oxidation of an alcohol can produce aldehydes‚ ketones‚ or carboxylic acids. One of the methods of oxidation is an aldol reaction through carbon-carbon bonds. The oxidation oxidizes primary alcohols to aldehydes and secondary alcohols oxidizes ketones. Tertiary alcohols are converted to the common oxidizing agents. Scheme 5.1: Aldehydes can be oxidized easily to carboxylic acids in aqueous medias

“Kinetics of Ethanol Oxidation” laboratory experiment utilized Beer’s law and spectroscopy to monitor concentration and the rate of ethanol oxidation through the LoggerPro System. This data then helped determine the kinetic rate constant‚ k‚ and the order of the reaction. First‚ the wavelength of maximum absorbance was determined using the LoggerPro interface and a Vernier colorimeter. Beer’s law was then used to determine the molar absorptivity. Finally‚ a kinetic study of ethanol oxidation was completed

Bleach Oxidation of 9-Hydroxyfluorene The purpose of this experiment was to oxidize an alcohol (9-hydroxyfluorene) to a ketone (9-fluorenone) using aqueous sodium hypochlorite (bleach) as the oxidizing agent‚ while introducing techniques used in microscale experiments. Reaction: Results 1. Recrystallized Product Yield Product yield = (actual yield/theoretical yield) x 100% 3mL 9-hydroxyfluorene x (1mL/1000mL) x (0.09 mol/L) = 2.7 x 10-4 moles 0.05g 9-fluorenone / (180.20g/mol) = 2.77 x 10-4

CHAPTER 2 AN INTRODUCTION TO COST TERMS AND PURPOSES 2-1 A cost object is anything for which a separate measurement of costs is desired. Examples include a product‚ a service‚ a project‚ a customer‚ a brand category‚ an activity‚ and a department. 2-2 Direct costs of a cost object are related to the particular cost object and can be traced to that cost object in an economically feasible (cost-effective) way. Indirect costs of a cost object are related to the particular cost object but cannot

Edwin compares the street address numbers of three of his neighbours with the quality of their front lawn‚ which he rates on a scale of 1 to 10. He observes a positive linear correlation and concludes that people with higher street address numbers have better lawns. In Edwin’s study: a) What are the independent and dependent variables? The independent variable is the street number and the dependent

An alcohol‚ any of a class of organic compounds characterized by one or more hydroxyl (−OH) groups attached to a carbon atom of an alkyl group (hydrocarbon chain). Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes‚ are valuable intermediates in the synthesis of other compounds‚ and are among the most abundantly produced organic chemicals in industry. Perhaps the two best-known alcohols are
