The vast number of hydrocarbons is indicative of the number of different ways the carbons skeleton can be arranged. Of these compounds, the simplest types are those that contain only hydrogen and carbon atoms. As for the ester with longer chain, the hydrocarbon portion forces itself between the water molecules and break the hydrogen bonds between the water molecules. Alkenes are readily reactive to bromine since its double bonds can be broken easily though addition reaction also is relatively similar if alkenes are added to potassium permanganate. Using (back to top) Lab Report Format. This template. Classes of Hydrocarbons Hydrocarbons can be divided into several di erent classes depending on the functional group present.

A short summary of this paper. The densities are the same for each with the exception chlorobenzene due to the hydrogen bonds that have to be broken, the dispersion forces that are acting upon the molecule as opposed to making new bonds in reacting water with chlorobenzene. ABSTRACT: Hydrocarbon are mainly the pollutants from oil refineries and oil spills. Alkyl groups are usually fairly resistant to oxidation. Under more vigorous conditions the geminal diol (from an alkene) that is initially produced will be further oxidized by the permanganate, producing more manganese dioxide. 1 In this experiment you will observe the solubility (a physical property) and the chemical reactivity of three different groups of hydrocarbons: alkanes, alkenes and aromatic compounds. The objective of this experiment is to identify the major hydrocarbons components in common fuels (diesel, petrol, thinner and an unknown) by using SPME-GC-MS. This experiment will examine how the di erent functional groups in Alkanes, Alkenes, Alkynes, and Aromatic hydrocarbons lead to di erent physical and chemical properties. Three fields of study are composed within this memo that includes Electrical Engineering, Environmental Engineering, and Petroleum Engineering. These are known as hydrocarbons. In order for this to “work” you should completely answer each of the questions in the order that they are asked before moving on to the next question. Ions and Compounds. Read Free Reports On Tensile Test Lab and other exceptional papers on every subject and topic college can throw at you. If it contains one or more carbon-carbon double bonds, it is classified as an alkene. Introduction - Hydrocarbons are the compounds containing only the hydrogen and the carbon elements. CHM510.
