that are already known. One type of which is the mostcommon and the simplest type that is only composed of hydrogen and carbon atom‚ the hydrocarbons.All hydrocarbons are insoluble in water due to their relatively non-polarity. Instead‚ they mix withrelatively non-polar solvents like dichlromethane or carbon tetrachloride. Hydrocarbons can be characterize on the way in which carbon atoms are connected‚ the aliphaticand aromatic hydrocarbons. Aliphatic hydrocarbons‚ from the Greek word aleiphar (fat

Hydrocarbons are compounds that contain only carbon and hydrogen atoms. Hydrocarbons may be divided into two large classes namely: Saturated hydrocarbons and unsaturated hydrocarbons. Saturated hydrocarbons are the simplest type of organic compounds. They are hydrocarbons in which all carbon- carbon bonds are single bonds. An example of a saturated hydrocarbon is an alkane. Unsaturated hydrocarbons are hydrocarbons that contain one or more carbon-carbon multiple bonds like double bonds‚ triple bonds

the definition‚ why‚ and for what purpose. The word "organic" is seen quiet frequently to represent whole foods that are made without preservatives and or pestecides. In actual fact organic means based on the carbon molecule. The word organic can be used commercially to pass off carbon based goods as healthy‚ which is not necessarily the case. In Neil Postman’s "Defending Against the Indefensible"‚ he suggests that our society has been culturally brainwashed. Therefore‚ Postman has given us seven

important materials in manufacturing tires‚ Natural Rubber and Carbon Black. Natural rubber is the basic elastomer used in tire manufacturing then synthetic rubber is often added by manufacturers to reduce cost. To avoid loss of quality‚ Carbon Black is then added which gives the final product reinforcement and abrasion resistance‚ it forms a high percentage of the rubber compound. Both can only be bought overseas‚ though Carbon Black supply is readily available in most of European countries

Banana (Musa Paradisiaca) Peel Shoe Polish | Abstract:Shoe polish is used to shine‚ to maintain the appearance and to sustain the quality of the shoes. Based on the information in the written articles‚ banana peels can be used to shine shoes so the researcher decided to come up with the study of making a shoe polish out of banana peelings. The study aimed to produce a cheaper but better alternative shoe polish.The researchers used banana peels‚ kerosene and candles in making the product. In making

Hypothesis: Suppose that the primary and secondary alcohols will react with HCL and KmnO4‚ and the tertiary alcohol wont react with either HCL nor KMnO4 due to the location of the OH. The carbon that is bonded to the OH in both primary and secondary still has one or two Hydrogen atoms to undergo reactions‚ but the carbon in the tertiary alcohol do not have any Hydrogen to undergo reactions with.

hydrochloric acid using nucleophilic substitution sn1. In the substitution reaction the Hydrogen in HCl protonated the alcohol group in t-pentyl alcohol and turned it to a good leaving group (H2O). a tertiary carbon cation was formed. a nucleophilic attach of the negative Cl- attacked the carbon cation forming t-pentyl chloride [7]. As the reaction proceeded‚ extraction and distillation techniques were used to get a pure product of t-pentyl chloride. The percent yield of t- pyntyl chloride (30.92 %
