Romero, Kristine S. Salvador School of Chemical Engineering and Chemistry, Mapua Institute of Technology, Intramuros, Manila, Philippines Experiment No. 3, Submitted on November 3, 2010 at N402 ABSTRACT Organic compounds with functional group, hydroxyl, were the center of study for this experiment. Both physical and chemical properties of alcohols and phenols are observed. From those observations, we can differentiate those two hydroxyl groups easily. For physical properties, we distinguish alcohols and phenols, based on their solubility in water. We also consider chemical properties such as acidity and its reaction with a certain reagent in distinguishing whether it is a phenol or alcohol. Additional test were also made in determination of the alcohol’s class based on their reactivity. For such tests, we use the reaction with sodium metal, acetyl chloride, bromine water ferric chloride, the Lucas test, its oxidation and iodoform test. Keywords: alcohols, phenols, classification tests, physical properties, alcohol class 1 INTRODUCTION [[[[[[[[[[insert your introduction]]]]]]]]]] Remove what is previously written here. . Kristine. . Ikaw na lang po bahala maglagay ng numbering sa mga pictures. . thanks. . e.g. Nilagay ko lng yan. .pakitanggal na lng Figure 1. Reaction of phenol with ferric chloride As what has been taught in chemistry lecture, there are over 20 million organic compounds identified. If each substance had to be studied as entity completely separate from all other substances, the study of organic chemistry as a whole would be impossible; that is to say, even more impossible than you currently believe it to be. Fortunately, the subject can be organized and it is systematized around the concept of the functional group. A functional group is an atom or group of atom, bonded together in a certain way that, as a part of a molecule, will impart certain physical and chemical characteristics to the molecule as a whole.

The functional group we are considering in this experiment is the hydroxyl (or hydroxyl) fuctional group, -OH. Among all hydroxyl groups, we have alcohol, enol, phenol, quinines, etc. And from those, we will just consider alcohols and phenols for this experiment. In alcohols, the –OH group is attached to a tetrahedral carbon atom. If the carbon atom is bonded to three hydrogens in addition to the –OH, the alcohol is methanol. If the carbon that is bonded to the –OH is bonded to one carbon and two hydrogens, the alcohol is primary (1 0 ) alcohol. If the carbon that is bonded to –OH is bonded to two carbons and one hydrogen, the alcohol is a secondary (2 0 ) alcohol. If the carbon that is bonded to the –OH is bonded to three carbons, the alcohol is a tertiary (3 0 ) alcohol. All of these alcohols share some characteristics but other
