Organic Chemistry is the study of compounds based on hydrocarbons and their derivatives. Unit 1: ... • The shells fill in order, from lowest energy level to highest energy level • All the elements in a group have the same number of electrons in their outer ... O . General Formula ( Cn H2n + 2 ) Functional Formula ( C – C ) Note: As boiling point of alkanes till Butane are below 0, therefore they are in gaseous form when at Room Temperature. Downward Delivery: Downward delivery is used …, February 16, 2016 Resonance, Acidity and Basicity Name the substance that reacts with ethene to make ethanol. For alkene, double bond position can be changed. Alkene reacts with water, in the form of steam, to produce alcohol. Are homologous series with general formula C, They have –OH functional group (hydroxyl group), First three members of the series (so that you’d have idea on the next), For alcohol, the –OH is not of hydroxide ion, OH. Only that their monomers consists of glycerol and fatty acids; different from terylene. A base is a a substance, that can accept H+ ions and therefore are proton acceptor. c. The diagram represents the structure of a common plastic. Starch can also be broken down into glucose by heating with sulfuric acid. Name a source of the methane required for this reaction. Usually in fuels, examples: natural gas, petrol, diesel, example: propane has three carbon atom, thus n=3. Sulfuric acid is added as catalyst then heat mixture. Oxygen is removed by limewater and carbon dioxide is produced during fermentation. What is the general formula of the alkene series? It is a colorless liquid with a boiling point of 100ºC. The particulate nature of matter; 3. to make ethene and another hydrocarbon as the only products. IGCSE revision book part 2. suggest why the term 'carbohydrate' is used for this type of compound. We can add sodium hydroxide and heat mixture to obtain carboxylic acid and alcohol from ester --> This is, Macromolecule is a large molecule made by joining together many small molecules, Polymer is a long-chain macromolecule made by joining together many monomers, Polymerisation is the addition of monomers to make one large polymer, Another ethene molecules add to this unsaturated compound during. produce toxic gas (such as hydrogen chloride) when burnt and this contributes to acid rain. 2, Salts: Salts are Ionic Compounds. Example: Copper(II) Oxide (CuO) Iron(III) Oxide (Fe2O3) Copper (II) Hydroxide (Cu(OH)2) Iron (III) Hydroxide (Fe2O3) It reacts with an acid to give salt and water only. Which compound is an unsaturated hydrocarbon? Give the full structural formula for the repeating unit in this polymer structure. b. Margarine is manufactured using the addition reaction between hydrogen and a vegetable oil. Therefore we can also call nylon as polyamide. hydrocarbons which the combining capacity of the carbon atoms is not fully used, e.g. ai. 0, Properties Of Ammonia: Colourless gas, with strong choking smell. Get free Kenyan K.C.P.E, K.C.S.E and Campus and College exam papers and KCSE revision materials. H H + . Glucose polymerise each other to form starch. Igcse Chemistry Revision Notes, O Level Chemistry Revision Notes a. alkanes with large molecules are not useful, b. small alkane molecules can be polymerised, c. crude oil does not contain small alkane molecules, d. to meet the demand for small alkane molecules, a. it is formed by the catalytic addition of steam to ethene, c. it is formed by the oxidation of ethanoic acid, d. it reacts with ethyl ethanoate to form an acid. Sign in|Recent Site Activity|Report Abuse|Print Page|Powered By Google Sites. b. I hope you find them useful. It covers alkanes, alkenes, alcoholc, carboxylic acids, ester, polymer and macromolecules. Description: This document contains a complete revision guide for chemistry at O-Level Cambridge Examinations on the Chapter Organic Chemistry. The total number of carbon and hydrogen atoms from products should equal to the total number of carbon and hydrogen atoms in cracked alkane. CIE O Level Notes. Butane cracks to form butadiene and one other product. Contact Process: Sulphuric Acid is manufactured using Sulphur, Air and Water. HClH+     +    Cl – H+ ion is proton Acids are called proton donors as provide H+   ions   General Properties: Turns Blue Litmus Paper Red. The mass of 1 litre of ethanol is 780 g. How much heat energy will be released when 1 litre (1dm, c. When completely burnt, 1 litre of gasoline releases 38000 kJ of heat energy. Reddish-brown colour of bromine disappears. Collection Of Gases: Upward Delivery: Upward delivery is used to collect gases that are less dense than air. Crude oil is mostly used as fuel, though some allocated for chemical feedstock. When there is insufficient oxygen, the product is ALWAYS carbon monoxide and unburnt carbon. Olive oil contains oleic acid which is unsaturated. i. 1, Sulphuric Acid: It  is a colourless oily yellow liquid, with density slightly higher than water.Having a boiling point of 338°C. There is too much of the heavier fraction of petroleum present.
