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

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

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

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 %

of energy consumption globally. Meanwhile‚ the fossil fuel mix is changing as well. Oil‚ still the leading fuel‚ has lost market share for 12 consecutive years. Coal was once again the fastest growing fossil fuel‚ with predictable consequences for carbon emissions [BP Statistical Review of World Energy‚ 2012]. Ethanol fuel is the most common biofuel worldwide‚ particularly in Brazil and USA which is produced from several biomass feedstocks and different technologies [].The ethanol production methods

Daniel Defoe Better a diamond with a flaw than a pebble without Confucius In mineralogy‚ diamond (from the ancient Greek αδάμας – adámas "unbreakable") is a metastable allotrope of carbon‚ where the carbon atoms are arranged in a variation of the face-centered cubic crystal structure called a diamond lattice. Diamond is less stable than graphite‚ but the conversion rate from diamond to graphite is negligible at standard conditions. Diamond

Alkynes are colorless and insoluble in water. The lower the members of alkynes (acetylene‚ allylene‚ and crotonylene) are gases. The homology from carbon number 5 to 15 (C5H8 to C15 H28) are liquid and the higher members are solid. Acetylene possesses a pleasant odor when pure. The impure acetylene contains phosphine‚ hydrogen sulphide etc and hence smells bad. Acetylene can be liqiufied at 0°C under 48 Torrs of pressure. The melting point of Acetylene is -81.8°C and boiling point -83.4°C. It is

Alkanes‚ alkenes‚ alkynes and aromatic rings are the four classifications of hydrocarbons. Each of these classifications have different physical and chemical properties that were tested as this experiment was performed. Flammability
