how they may be manipulated and changed. Although organic reactions have been conducted by man since the discovery of fire‚ the science of Organic chemistry did not develop until the turn of the eighteenth century‚ mainly in France at first‚ then in Germany‚ later on in England. By far the largest variety of materials that bombard us are made up of organic elements. The beginning of the Ninetieth century was also the dawn of chemistry‚ all organic substances were understood as all being materials

Amanda Jornd Experiment 7- Synthesis and Reactivity of tert-Butyl Chloride Via an SN1 Reaction Introduction/Background: Alkyl halides are compounds in which a halogen atom replaces a hydrogen atom of an alkane. Alkyl halides are classified as primary‚ secondary or tertiary depending on the number of alkyl substituents directly attached to the carbon attached to the halogen atom. The purpose of this lab was to properly prepare t-butyl chloride from t-butyl-alcohol in a concentrated hydrochloric

Comparison between Organic and Inorganic Compounds Organic Compounds | Inorganic Compounds | *Organic Compounds are composed of few elements only.C‚ H‚O‚N‚S‚P and halogens are the most common. | * Inorganic Compounds are composed of all the known elements. | *They are generally found in living matter‚ i.e.‚ animals and plants. | *They are generally obtained from non-living matter‚ i.e.‚ minerals. | *They are usually gases‚ liquids or solids having low melting points. | *They are usually solids

Identifying Organic Compounds 2. Purpose/Problem: I am doing this experiment to find out what kind of organic compounds are in test tubes A‚ B‚ C and D. I am curious to know if substance D was the lipid because it seemed thin and had a slightly yellow tint of color to it. 3. Research: In my research I was informed about facts and appearances of lipids. First of all lipids are non-polar compounds‚ thus they won’t dissolve in water. This is also known as being hydrophobic. They are made with one

Trends in the Periodic table March 24‚ 2013 Four trends that will be covered: Atomic size Ionization Energy Electronegativity Electron Affinity Each of these has a group trend and a period trend A group trend refers to what is happening with the atom as you travel up or down a column of the periodic table. A period trend refers to what is happening with the atom as you move left or right across a row of the periodic table Atomic Size When discussing an atom’s size‚ usually the

Liquid Nitrogen Randi Pinter Community College of Aurora Rebecca Hoenigman Chem 101-360 Sitting in a classroom with a guest speaker‚ wondering what was in the tank and why there were carnations nearby. As a young student‚ guest speaker days were an exciting thing to be a part of. The full history of the lesson may have been lost in time; but when the speaker dipped a carnation in a tub of liquid that was pouring smoke onto the classroom floor‚ the results of his actions had the power to make a

A carbohydrate is an organic compound that consists only of carbon‚ hydrogen‚ and oxygen‚ usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words‚ with the empirical formula Cm(H2O)n. The carbohydrates (saccharides) are divided into four chemical groupings: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. In general‚ the monosaccharides and disaccharides‚ which are smaller (lower molecular weight) carbohydrates‚ are commonly referred to as sugars.

Surface Tension Properties of Liquids Introduction The purpose of this experiment is to measure and record the surface tension of water and other aqueous solutions using capillary rise method techniques and practicing lab safety. In this laboratory the surface tension of water depends on the concentration of the following solutes; NaCl‚ acetone‚ and sodium dodecyl sulfate (SDS). Intermolecular interactions as well as other phases (solid‚ or air) make a liquid exist. The data collected will show
