Alkanes are saturated hydrocarbons. They contain only carbon-carbon and carbon-hydrogen single bonds. They are the least reactive of the organic compounds. The main source is crude oil. Hydrocarbon- a compound consisting only of hydrogen and carbon Saturated- Contain single carbon -carbon bonds only Unsaturated-contains a C=C bond Petroleum fraction- mixture of hydrocarbons with a similar chain length and boiling range The general formula for is CnH2n+2 (for ring alkanes is CnH2n)

During an EPA compliance inspection‚ the concentration levels of PAH were above the prescribed limit. Polycyclic Aromatic Polycarbons are pollutants that have been identified as carcinogenic‚ mutagenic‚ and teratogenic. PAH are produced as byproducts of fuel burning and can be found in foods and water. Alumina quickly complied and was said to be within compliance

phenols to be associated and‚ therefore‚ to have higher boiling points than hydrocarbons of the same molecular weight. Thus‚ phenols have a modest solubility in water. Although phenols are structurally similar to alcohols‚ they are much stronger acids‚ however they are weaker acids compared to carboxylic acids. In the experiment‚ the following samples of aldehydes are used‚ 1) Benzaldehyde It is the simplest aromatic aldehyde. It is employed to confer almond flavor. It is used chiefly as a

developed from knowledge of the structure of a carbon atom and how it can combine with other carbon atoms by forming covalent bonds. Alkanes Alkanes are hydrocarbons‚ which are molecules that contain only carbon and hydrogen. They are made up of carbon atoms linked together by only single covalent bonds and are known as saturated hydrocarbons. Many alkanes are obtained from crude oil by fractional distillation. The smallest alkanes are used extensively as fuels. Apart from burning‚ however

The most common chemicals involved are petroleum hydrocarbons‚ polynuclear aromatic hydrocarbons (such as naphthalene and benzo(a)pyrene)‚ solvents‚ pesticides‚ lead‚ and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical usage. There are many different ways of permanently

Abstract The experiment: Classification tests on Organic Compounds‚ allows the students to be familiarized with different classification tests used for identifying the different classes of organic compounds; examine unknown compounds using appropriate tests; and identify functional group of an organic compound based on the tests performed. Several organic compounds with different functional groups were tested to identify the functional groups present in the compound. n-heptane‚ pentene

The importance of safety in the Fire Service Fire safety is very important in the field of fire fighting. Safety needs to be respected by everyone who works together or else something can go wrong. Firefighter safety is an essential part of the job. Some of the safety precautions used by departments are intended to prevent firefighters from injuring themselves and to protect their lives. In this essay I will talk about the importance of using SCBA and the importance of maintaining
