Higher alkanes up to those having 17 carbon atoms are liquids; higher alkanes are solids at room temperature. I have covered all the organic chemistry basics with a complete breakdown. Cracking produces a mixture of alkanes and alkenes. The orange bromine water is decolourised in the process. I stumbled across the notes on the web and they were a lifesaver last semester. Alkenes: alkenes are more reactive than alkanes due to the presence of carbon to carbon double bond as the functional group. The number of carbons atom(s) in the compound. The name of an organic compound indicates four things: The number of carbon atom(s) present is indicated by the prefix (beginning part of name). Car engines also require a lot of air and there is a lot of research going on to make the internal combustion engine more efficient, and so put out less carbon monoxide. Alkanes: alkanes are the most inert of all the homologous series, due to the presence of only C-H bond which is quite stable or inert. The laboratory equipment to produce ethene gas is shown below. So, "Stop Writing, We've Already Taken Your Notes." For example, the General Formula of Alkane is CnH2n+2 . This is because from cracking, we get many types of molecules. The monomers are of the same types; they join up to form a polymer. Hydrocarbons, which contain two hydrogen atoms less than the corresponding alkanes, are called alkenes. Crude oil is heated until it boils and then the hydrocarbon gases are entered into the bottom of the fractionating column. This means, if an alkane has one carbon atom, then it will have 2(1)+2 = 4 Hydrogen atoms. ), 18 - Aldehydes and Ketones: Nucleophilic Addition Reactions, 20 - Carboxylic Acid Derivatives and Nucleophilic Acyl Substitution Reactions, 21 - Carbonyl Alpha-Substitution Reactions, choosing a selection results in a full page refresh. The position no. We can use the general formula of alkane to easily figure out its molecular formula. Crude oil simply contains alkanes and alkenes of various sizes, all mixed together. Ethene is used for manufacturing organic compounds such as ethyl alcohol and ethylene glycol. The Homologous series is a family or group of hydrocarbons or derivatives having the same functional group, same general formula and similar chemical properties. The oil and natural gas become trapped underground. All the carbon atoms cannot get oxidized while burning this makes the flame sooty. This would be extremely difficult to draw out and so the structure is often shortened to a, There are 3 stages to think about when drawing a repeat unit for a polymer -. The gases are then passed over water. Fossil fuels are a finite resource and non-renewable. have oxygen added to it. The molecular formula represents a summary of all the atoms in the molecule. Use the organic chemsitry notes and study guides to learn the concepts of organic chemsitry easily and fast. Compare Quick view. Organic compounds which are in the same homologous series show a similar trend in physical properties. I am the author of IGCSE and IAL Chemistry website. Ethyne combined well with oxygen can burn to give a flame whose temperature is 3000. For example, the melting and boiling points of alkanes increases as their carbon number increase (or their size increases). There is no byproduct. Butene has four carbon atoms, hence n=4. AC SIR ORGANIC CHEMISTRY NOTES ₹ 600.00 – ₹ 1,100.00. The larger fractions are quite unreactive and cannot be used as fueld, for this reason they must be cracked. No more, no less. This is why ignition sources (such as smoking) are not allowed at petrol stations. Each family of organic compounds forms what is called a homologous series. The number of Carbon atoms are 4, hence n=4. Also in some cases, it gives rise to some unique physical properties too. We can easily use the general formula of alkene to determine the molecular formula of butene. They distill what your lecturer is saying down something that can be more clearly understood. The hydrides of carbon (hydrocarbons) and their derivatives are called organic compounds. When an organic compound is unsaturated (contains carbon to carbon double bond). Ethanol is used as biofuel, it is renewable and produced by fermentation. The homologous series to which the compound belongs to is indicated by the suffix (end part).

If you are an IGCSE Chemistry student desperately looking for the perfect organic chemistry notes, then this is the one! The purple manganate (VII) solution is decolourised during the reaction. This is known as the process of hydrogenation. Download Pharmaceutical Organic Chemistry Notes. There are two types of polymerization, addition polymerization, and condensation polymerization. Aniline – Lab preparation, Properties, Reactions and Uses. The carbon-carbon double bond may also be oxidised i.e. Hydrocarbons that have two carbon atoms in a triple bond are called alkynes. Gives its own chemical property. If an alkyl group attached or not. Do not worry if you are still confused about what a functional group is. The functional group of alkenes gives it some unique chemical properties. The smaller the hydrocarbon molecule, the further it rises up the column before condensing. Download Chemistry Form 3 Notes PDF to Print or Offline Reading. no more atoms can add to it. As the gases go up the column the temperature decreases. But they will react with strong oxidising chemicals like chlorine when heated or subjected to u.v light. Isomers are simply organic compounds with same molecular formula but different structural formulas.

Ethyne is also used making many industrially useful organic compounds like acetaldehyde, acetic acid, etc. All notes will be available very soon. Download Organic Chemistry Notes for immediate use. IB chemistry standard level revision notes on organic chemistry Home: syllabus: faq: download ... Organic Chemistry (sl) 10.1 - Introduction: 10.2 - Alkanes: 10.3 - Alkenes: 10.4 - Alcohols: 10.5 - Halogenoalkanes: 10.6 - Reaction pathways: 10.1 - Introduction . The reaction is shown below. This organic chemistry note for IGCSE chemistry covers the three major homologous series Alkane, Alkene, and Alcohols. they have a prefix (meth-, eth-, prop-, but-, etc. Download Pharmaceutical Organic Chemistry Notes Free For B.Pharm and D.Pharm students. Organic Chemistry is the study of compounds based on hydrocarbons and their derivatives. I have helped many students get good grades in their chemistry exams. We will discuss their general formula, physical and chemical properties. Ask a question related to this topic in the comment section below. We are going to learn about four main homologous series; they are Alkane, Alkene, Alcohol and carboxylic acid. If you want to learn the basics of Hydrocarbons, then you can also have a look at my blog “Hydrocarbon Classification, Names and General Formulas“. It provides no information about the type of bonding between the atoms. Ethene gas starts evolving and it can be collected over water by downward displacement of water. If catalysts are not used, then the higher temperature is needed, which is a waste of energy.
