From this repeat unit, to find the monomer formula, we add double bond between C – C and remove the bonds on each of their sides. Igcse Chemistry Revision Notes, O Level Chemistry Revision Notes We have both General Chemistry Notes and Organic Chemistry Notes. Fats can also be broken down to sodium salts of fatty acids and glycerol by boiling it with an acid or alkali. The following terms are used in the description of organic compounds. Heptane is an alkane with seven carbon atoms per molecule. Alkene reacts with water, in the form of steam, to produce alcohol. Proteins can also be broken down into amino acids by boiling protein with sulfuric acid. Then the formula of propane is C, Shows how all atoms in a molecule joined together by drawing lines between atoms to represent the bonds, Organic compound containing only single bond is saturated Eg: methane -, Melting points and boiling points increase as the bonds become larger and heavier which increases the forces of attraction between molecules so more energy (from heat) is needed to separate them with the increase of strength of forces of attraction, insoluble in water but soluble in organic solvents such as tetrachloromethane as alkanes are organic compounds, density increases down the series; all alkenes are less than 1g/cm, become more viscous going down the series as the longer molecules tangles together when it flows, become less flammable down the series as boiling point increases, unreactive with either metals, water, acids or bases because the C – C and C – H covalent bonds are harder to break, Have same chemical properties – they don’t react with most chemicals. This organic chemistry note for IGCSE chemistry will cover the three major homologous series Alkane, Alkene, and Alcohols. The product is carboxylic acid and water. Tips and notes for English, General Paper, and … hydrocarbons which the combining capacity of the carbon atoms is not fully used, e.g. Comparing ethanol and gasoline as liquid fuels, suggest, i. one advantage of using ethanol rather than gasoline, ii. The syllabus includes the main theoretical concepts which are fundamental to the subject, a section on some current applications of chemistry, and a strong emphasis on advanced practical skills. boiling point).

Chemistry Revision Notes 2012. Proteins have similar linkage to that of a nylon. An Introduction to Organic Chemistry 88 Example two: C 2H 6O CH 3CH 2OH CH 3OCH 3 C C O H H H H H H C O C H H H H OH O Both exemplify structural isomerism. Chapter 1 - Measurements in Chemistry; ... Part 7 - Organic Chemistry. Give one other general characteristics of homologous series. A Salt contains a positive metal ion and a negative non – metal ion. Due to different chain length, they have different physical properties (e.g. A-Level Chemistry. You can find notes and exam questions for Additional math, Elementary math, Physics, Biology and Chemistry. When dissolved in water, they can conduct electricity. b. …, February 15, 2016 7a. Our organic chemistry notes are actual, perfectly-neat, handwritten notes that have helped thousands of students obtain the organic chemistry help they need. 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. Briefly describe the manufacture of ethanol from glucose. When there is insufficient oxygen, the product is ALWAYS carbon monoxide and unburnt carbon. Alkenes react with hydrogen to form alkanes, called hydrogenation. Providing study notes, tips, and practice questions for students preparing for their O level or upper secondary examinations.
