Alkene Nomenclature -Hydrocarbons Notes

Do you know !! What are alkenes? The class of hydrocarbons which contains at least one carbon-carbon double bond are called alkenes. Their functional group is C=C They have at least one carbon-carbon double bond. Alkenes have hydrogen atoms less than the corresponding alkanes. Alkene also forms a homologous series and each member of the …

Uses of Alkanes – Hydrocarbons Notes

Do you know!!! Uses of Alkanes: Following are the uses of alkanes. Alkanes are used as fuel. e.g. refinery gas, gasoline, kerosene oil, diesel oil all are mixture of alkanes and are used as fuel. By catalytic oxidation of alkanes fatty acids (carboxylic acids) are prepared which are used in soap and vegetable oils. By …

Chemical Properties of Alkanes | Halogenation and Oxidation in alkanes

Chemical Properties of Alkanes:: Alkanes being saturated compounds mostly show substitution reactions. Their oxidation is very difficult thus even strong oxidizing agents like KMnO4, K2Cr2O7 etc cannot oxidize them. Halogenation: Halogens replace hydrogen from alkanes and it is called halogenation of alkanes. The order of reactivity of halogens with alkanes is F2>Cl2>Br2>I2 Fluorine shows a …

Free Radical Substitution, Electrophilic Substitution and Nucleophilic Substitution Reactions Notes

Do you know!! What is substitution reaction? “The chemical reactions in which an atom or group of atoms directly attached to the carbon in the substrate molecule is replaced by another more reactive atom or group of atoms are called substitution reactions”. Substrate: The molecule in which substitution takes place is called a substrate. Example: …

Naming of Organic Compounds | Common vs IUPAC Nomenclature Notes

The naming of organic compounds: Nomenclature: The systematic process of naming organic compounds is called nomenclature. At the beginning of organic chemistry, each new compound was given an individual name. These names were based on : 1.its source  2.property 3.on the name of the discoverer 4.based on history 5.method of preparation For Example: Formic acid, …
