INTRODUCTION Hydrocarbons are compounds that consists carbon and hydrogen only. They are the simplest organic compounds. Hydrocarbons‚ because of their number and variety‚ are classified into different ways. One way of classifying hydrocarbons is in which way carbon atoms are connected. It can be classified as either a chain aliphatic hydrocarbon or a cyclic hydrocarbon. Chain aliphatic hydrocarbons are compounds that are linked either in a single or branched chain. An example of this is hexane

isotopic dating is recognized as carbon dating. The radioactive decay of carbon-14 is used in carbon dating. Carbon-14 atoms are equally distributed over Earth ’s biosphere. These atoms are combined with carbon-12 and carbon-13. Organisms contain the same ratio of carbon-14 to carbon-12 and carbon-13 because organisms are always taking in carbon. When the plants intake carbon dioxide‚ they are using these various carbon isotopes. When a plant is eaten by an animal‚ the carbon-14 atoms are then transferred

Thickness: 12mm Thickness of base: 10mm No. of mounting points: 4 No. of holding holes: 2 Diameter of the holes: 65mm each. The proposed design uses high carbon steel instead of low carbon steel‚ this increase strength and rigidity of the compacted bracket design. The composition of high carbon steel contains 0.55% - 0.95% carbon‚ with 0.30% - 0.90% manganese‚ that

with compounds of Carbon. 2.Carbon’s has 4 valence electrons that can form covalent bonds with others atoms (Hydrogen‚ Nitrogen‚ Oxygen and Carbon atoms mostly) to make large‚ complex and diverse organic molecules. 3.The carbon skeleton vary in 4 areas‚ 1. Length 2. Branching 3. Double Bond Position 4. Presence of Rings. Carbon skeletons can have double bonds in different locations and also different numbers of double bonds. 4.Hydrocarbons only have hydrogen and carbon molecules‚ hence

Our Infrared Spectroscopy (IR) spectrum for our Acetaminophen KBr pellet provided a handful of strong peaks and hints that helped us to hypothesize what functional groups might be in Acetaminophen. The peaks that were at the highest wavenumbers were analyzed first. The strong peak at 3325.82 cm-1 was an indicator that there was stretching occurring between a Hydrogen and Nitrogen atom. This signified that Acetaminophen could contain an amide group. The next defined peak is located at 3162.26 cm-1

Testing for functional groups The chemistry for carbon is vast; there are in excess of ten million known carbon compounds. It is estimated that 300000 new carbon compounds are discovered each year. Organic molecules contain functional groups that are responsible for their chemical properties. Functional groups will react with certain regents in predictable ways‚ making it possible to develop diagnostic reactions to test for their presence in an organic molecule. Common functional groups found

Nano tubes are molecular-scale and are wrapped with graphitic layers. http://ipn2.epfl.ch/CHBU/NTprimer.htm http://ipn2.epfl.ch/CHBU/NTprimer.htm They are called “Nano” because of their sizes that are roughly billion times smaller than a meter. Normally they are very thin and have hollow cylindrical structures made out of carbon atoms. However‚ they still exist in

was obtained from the distillation of coal in the absence of air. Today most benzene is made syntheticallyfrom petroleum products. The benzene is a closed ring of six atoms connected by bonds that resonatebetween single and double bonds; each carbon is also bound to a single atom. Benzene isinsoluble in water but mixes in all proportions with organic . Benzene is itself an excellentsolvent for certain and for most simple organic chemicals. It is one of the most commonly used solvents in
