* Introduction to Organic Chemistry Understand the basis of drawing organic structures Depicting 3-D structures in 2-D Most organic compounds have a three-dimensional structure. How do we represent structures on our two-dimensional page? For example‚ methane is a tetrahedral molecule: Bonds in the plane of the paper: Bonds coming towards the observer: (out of the page) Bonds going away

www.igcse.at.ua ORGANIC CHEMISTRY OIL and its many useful PRODUCTS The origin of oil Crude oil is formed from organic material of the remains of plant and animal organisms that lived millions of years ago. These remains form sediments eg at the bottom of seas‚ and become buried under layers of sedimentary rock. They decay‚ without air (oxygen)‚ under the action of heat and pressure to form crude oil over millions of years. It is a fossil fuel because it is formed from

educator Friedrich Froebel designed‚ the organic unity of a Japanese building Wright saw at the Columbian Exposition in Chicago in 1893‚ and a Jeffersonian belief in individualism and populism. Always a believer in architecture as "natural" and "organic‚" Wright saw it as serving free individuals who have the right to move within a "free" space‚ envisioned as a nonsymmetrical design interacting spatially with its natural surroundings. He sought to develop an organic unity of planning‚ structure‚ materials

CLASSIFICATION TESTS A. Acids There are relatively few suitable tests for carboxylic acids. Classification is based mostly upon solubility tests. If the compound is water soluble‚ test the aqueous solution of your compound with pH paper (also check the pH of the original water). If the compound is water-insoluble and it dissolves in 5% (1.5M) sodium hydroxide and 5% NaHCO3 solutions as performed in your solubility tests‚ it can be classified as a carboxylic acid. Establish an equivalence value

a 50/50 (% volume) mixture of petroleum ether and acetone. Cap the centrifuge tube and shake until the solid becomes fluffy. Open the cap and crush the solid with a spatula. Close the tube and shake again. Repeat this crushing and shaking two more times. Centrifuge the tube to separate the extract and residue. Remember to balance the centrifuge so that it does not walk (perhaps you and your neighboring lab group can share and balance each other’s tubes) and do not stop the centrifuge with your fingers

Organic chemistry Organic chemistry is one of the ‘branches’ of chemistry and is seen as distinct from other branches‚ such as inorganic and physical chemistry. It can be described as the chemistry living processes (often referred to as biochemistry) but extends beyond that. It focuses almost entirely on the chemistry of covalently bonded carbon molecules and as well as life processes‚ it includes the chemistry of other types of compounds‚ including plastics‚ petrochemicals‚ drugs and paint

success as cyclohexene was produces from cyclohexanol. Introduction On a general level‚ alkenes can be formed from the dehydration of an alcohol in the presence of a strong acid. The acid simply acts as a catalyst and as such increases the reaction time but while doing so does not affect the overall stoichiometry. The usual mole ratio of such reaction is therefore 1:1 which means that the theoretical yield of Alkene in mole is equal to the amount of alcohol used in the reaction. Below are the reaction
