Prospect Introduction A. Background of the study A plastic is a type of synthetic or man-made polymer; similar in many ways to natural resins found in trees and other plants. Webster’s Dictionary defines polymers as: any of various complex organic compounds produced by polymerization‚ capable of being molded‚ extruded‚ cast into various shapes and films‚ or drawn into filaments and then used as textile fibers. Plastics are durable that is why most of the stuffs we see nowadays are made from

very poisonous‚ and can cause burns. Eyes‚ skin and nose should be protected while carrying the bromine inside the hood. Glacial acid is also a very corrosive compound and can cause severe burns when it’s reacting with aromatic compounds. Also‚ the organic waste was disposed in the halogenated waste container. Procedure: In a reaction tube‚ 0.05 g of acetanilide is added and the exact mass is recorded. In the same reaction tube‚ 8 drops of glacial acid is added carefully inside the hood‚ and stirred

IS PLASTIC BAD FOR THE ENVIRINMENT? A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass‚ but they often contain other substances. They are usually synthetic‚ most commonly derived from petrochemicals‚ but many are partially natural. Whether you are aware of it or not‚ plastics play an important part in your life. Plastics’ versatility allow it to be used in everything from car

INTRODUCTION Hydrocarbons are organic compounds that consist of only C and H atoms. They include the alkanes‚ 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

8. Terfenedine is an amino diol that is the active ingredient in the antihistamine Seldane. Mass spectral analysis of terfenedine shows a molecular ion at m/z = 471 and a peak at m/z = 472 which is 35.5% the height of the molecular ion. Terfenedine is known to contain C‚ H‚ O and N. (a) Suggest five molecular formulas for terfenedine. (b) Terfenedine has an even number of carbons and contains nine double bonds and four rings. Based on this additional information‚ what is the formula for terfenedine

point of the isolated products were measured against the standards in order to determine how strong of an ortho/para activator the compound was based on the product(s) and melting point obtained. Theory: Electrophilic aromatic substitution is an organic reaction that takes place when an atom that is bound to an aromatic ring is replaced by an electrophile. The electrophile replaces a hydrogen atom on the ring. When a substituent group is present on the original compound‚ this substituent affects
