Properties and Reactions of Hydrocarbons
The goal of experiment 1 was to determine the properties and reactions of hydrocarbons. This was achieved by testing solubility and observing the effects of different interactions between solvents and isooctane. Overall procedures involved mixing 9 different solvents with isooctane and observing solubility with the naked eye. It was concluded that 5 of the combinations proved soluble, 2 completely insoluble, and 2 were insoluble at room temperature but soluble if heated. Also tested was the reactivity of cyclohexane and cyclohexene in sulfuric acid which tested to prove reactivity between cyclohexene but not cyclohexane. Finally tested was the reaction between bromine and alkenes, which showed reaction between the more polar alkenes than non polar. Introduction

In part one of the experiment, 9 solvents were placed in sample vials in 1 mL increments. Solvents used were water, methanol, n-butanol, ethylene glycol, acetone, hexane, toluene, ethyl acetate, and dichloromethane. Then added to the vials was 0.5 mL of isooctane in each one. The vials were then swirled and observed to determine solubility. In part two of the experiment, 0.5 mL of concentrated sulfuric acid was added into two sample vials, and 0.5 mL of cyclohexane was added to one, and 0.5 mL of cyclohexene was added to the other, and they were both swirled to observe reactivity. Part three of the experiment involved placing 1 mL of dichloromethane in each of five sample vials followed by adding 5 drops each of cyclohexene, toluene, beta-pinene, camphene, and trans-stilbene to the vials and swirling each until dissolved. Then bromine solution was added to each vial and observed. Experimental Section

Part one of the experiment consisted of obtaining a vial stand and placing 1 mL of water, methanol, n-butanol, ethylene glycol, acetone, hexane, toluene, ethyl acetate, and dichloromethane one each into 9 vials. Proceeded by this was adding...
