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

Properties of Alcohols and Phenols Experiment #3 Objectives: To observe the solubility of alcohols relative to their chemical structure‚ to perform chemical tests to distinguish primary‚ secondary and tertiary alcohols‚ and a color test for phenol. Introduction The general formula of an alcohol is ROH in which the R is an aliphatic hydrocarbon group. Alcohols may be looked upon as derivatives of water‚ HOH. One hydrogen of water is substituted by an alkyl group‚ R. Like water‚ alcohols show hydrogen

Combustion Of Alcohols Planning This investigation involves burning alcohol in the air. Key science- Chemistry by Eileen Ramsden says that " an alcohol is a series of organic‚ homologous compounds‚ with the general formula Cn H2n+1OH". The alcohol reacts with the oxygen in the air to form the products water and carbon dioxide: Cn H2n+1OH +(n+n/2)-1O2 ? nH2O + nCO2 The structure of the molecules in this reaction is: H H | | H - C - C - O- H + 3[O=O] ? 1/2[O=C=O] + 3[H-O-H] | | H H This reaction
