Organic compounds hexane, heptane, cyclohexane, cyclohexene, benzene, and toluene were subjected to different physical and chemical tests todifferentiate their intrinsic physical properties and chemical properties in terms ofstructure and behaviour. Nitration test (test for the presence of aromatic ring), Bromine test (test for the presence of unsaturation), and Basic oxidation test (test for an alkyl substituted benzine) were done. We were given an unknown which we tested (Nitration,Bromine, Basic oxidation) and found out that it was an aromatic unsaturated hydro carbon.

Keywords: hydrocarbons, hexane/ cyclohexane, cyclohexene, naphthalene, toluene

1. Introduction

This experiment aims to differentiate the different types of hydrocarbon as well as to identify the unknown through parallel chemical test. In this experiment we were expected to characterize hydrocarbons based on their chemical reactions.

Hydrocarbons are organic compounds that consist of only C and H atoms. They include the alkanes, alkenes, alkynes, and aromatic hydrocarbons. Because of their relatively nonpolarity, all hydrocarbons are insoluble in water. Hydrocarbons may be divided into two large classes namely: Saturated hydrocarbons and unsaturated hydrocarbons. Saturated hydrocarbons are the simplest type of organic compounds. They are hydrocarbons in which all carbon-carbon bonds are single bonds. An example of a saturated hydrocarbon is an alkane. Unsaturated Hydrocarbons are hydrocarbons that contain one or more carbon-carbon multiple bonds like double bonds, triple...
