REACTIONS OF HYDROCARBONS Vanessa P. Manibpel De La Salle University - Dasmariñas ABSTRACT Five substances namely Hexane‚ Eugenol‚ Unknown hydrocarbon 1‚ Unknown hydrocarbon 2‚ and Acetylene gas was used for the selective reactivity of hydrocarbons to functional group tests; Bayer’s test‚ Bromine test light‚ Bromine test dark‚ and Tollen’s test. In Bayer’s test‚ only Acetylene‚ Eugenol and Unknown hydrocarbon 2 reacted positively and the rest retain the purplish color of KMnO4. On the other hand

Properties and Reactions of Hydrocarbons Abstract Introduction Hydrocarbons are organic materials that contain only carbon and hydrogen atoms‚ these molecules can be saturated or unsaturated and acyclic‚ cyclic‚ or aromatic. In this experiment we used a variety of methods to examine the physical and chemical properties of hydrocarbons. The first experiment we tested a variety of solvents to see if they dissolved our alkane (Decalin). One would expect that non-polar solvents will dissolve alkanes

Title : Properties of hydrocarbon Objective : 1) To study the properties of hydrocarbons. 2) To determine the unknown samples. Results : Part A : Combustion Compounds Observations Hexane There was orange flame and burned mildly during the burning process. No soots and smoke were produced. C6H14 + 19/2 O2 6CO2 + 7H2O Cyclohexene Orange flame burned vigorously. A small amount of black soot and smoke were produced during the burning process.

com Liquid Chromatography AP Chemistry Laboratory # 18 Publication No. 10535A Catalog No. AP9093 Introduction In this experiment‚ liquid chromatography is used to separate the substances that are present in grape-flavored Kool-Aid®. First‚ the dyes responsible for the purple color‚ FD&C Blue #1 and Red #40 are separated. Then‚ in a second experiment‚ the other components of Kool-Aid®‚ the flavorings and citric acid‚ are separated as well. Concepts • Resolution • Liquid chromatography • Selectivity

Column Chromatography of Plant Pigments Paul Ibarbia‚ Gene Paolo Jasmin‚ Gianpaolo Jimenez and Lorenzo Labicane* Department of Biology‚ University of Santo Tomas‚ Manila‚ Philippines Abstract Column chromatography of plant pigments is the separation of plant pigments extracted from Capsicum frutescens (siling labuyo). No slurry is prepared of the eluent; eluent with the stationary phase is set and then carefully poured into the column. The eluent are the solvents which are responsible for the

Are Aromatic Hydrocarbons Carcinogenic Aromatic hydrocarbons or arenes are hydrocarbons characterized by alternating double and single bonds between carbons. Benzene is the most common aromatic hydrocarbon‚ but there are some non-benzene based compounds called heteroarenes‚ where a carbon is replaced by an oxygen‚ nitrogen‚ or sulfur‚ that are also aromatic compounds. Aromatic hydrocarbons exist in our daily lives regardless if we recognize them or not. Aromatic hydrocarbons are ingested or

Analysis of Hydrocarbons Myra Gurango‚ Geneva Guy‚ Micah Hernandez* and Joyce Lagarde Department of Chemistry‚ University of Santo Tomas‚ Manila‚ Philippines Abstract The organic compounds hexane‚ toluene‚ cyclohexene and naphthalene in hexene were subjected to parallel chemical testing to differentiate their intrinsic physical properties in terms of structure and behavior. The physical state and color were noted by simple physical observation. Nitration Testing was conducted for preliminary

Analysis of Hydrocarbons Jennifer Alambra‚ Ma. Nancy Anulat‚ Alfonso Apepe*‚ Jacqueline Arsenal 3Bio4 Department of Biological Sciences - College of Science‚ University of Santo Tomas‚ Manila ABSTRACT The unknown hydrocarbon sample was differentiated and characterized by the use of three tests. The outcomes of these tests are as follows: Nitration test (negative)‚ Bromine test (positive) and Basic Oxidation test (positive). From these results the unknown sample can be classified
