alkenes‚ alkynes‚ and aromatic hydrocarbons. Because of their relatively non-polarity‚ all hydrocarbons are insoluble in water. When hydrocarbons burn in sufficient oxygen‚ carbon dioxide and water are the sole products. The main structural difference among hydrocarbon families is the presence of double or triple bonds between carbon atoms. The alkanes are saturated organic compounds‚ or those with only single bonds. Unsaturated organic compounds are those which have double or triple bonds. [1] Many

Identification of the side-chains. Side chains are the carbon chains that are not in the parent chain‚ but are branched off from it. 4. Identification of the remaining functional groups‚ if any‚ and naming them by the their ion names (such as hydroxy for -OH‚ oxy for =O‚ oxyalkane for O-R‚ etc.).

BOILING POINTS AND MELTING POINTS PART 2 Name: Grethel Zegarra Date of Lab: October 26‚ 2010 Date lab is due: November 2‚ 2010 HYPOTHESIS The boiling point in degrees Celsius will increase as the number of carbon atoms increase. The melting point of the unknown will indicate its mixed substances. The boiling point will increase as a result of the different branching of the OH‚ the melting point will be affected by the different positioning of the OH on the benzene ring. PURPOSE To introduce

Cars diving around create food for plants to turn the carbon waste in to air‚ but there is also the fact of the car that leaks oil or gas on the ground and making a chemical waste pollution. This waste can be very damaging to an ecosystem to the point that it can kill the wildlife‚ plant life‚ and even hurt

We are “star stuff”. Discuss in detail our connections to the stars as established by modern astronomy. Modern astronomy has allowed us to understand how the universe functions and also provides the answers to some of the big questions. Questions like the origin of the universe and origin of life itself. It tells us that stars are the cosmic furnaces where all most all the building blocks of life and planets were synthesized.

Organic compounds are based on carbon these are found only on living things. Inorganic is the opposite it doesnt come from living things its from synthetic fibers like polyester or nylon are carbon based but are not found in plants or animals. From a forensics science point of view both inorganic and organic compounds are very important when found in items of evidence

hydrocarbon accumulation Phases of alteration of organic matter Types of kerogen Migration of hydrocarbons Five Major Types of Hydrocarbons Kerogen: Kerogen is a fine-grained‚ amorphous organic matter. It is not soluble to normal petroleum solvents‚ like carbon disulfide. Its chemical composition is 75% C‚ 10% H‚ 15% other (sulfur‚ oxygen‚ nitrogen‚ etc.). It is very important in the formation of hydrocarbons because it is what generates oil and gas. Source rocks must contain significant amounts of kerogen
