Polymerisation of Alkenes The polymerisation is a process of combining monomer molecules together in a chemical reaction to form polymer chains. The molecule of alkenes can combine together through addition reaction to form a long chain polymer. In the reaction, alkene molecules undergo addition reaction at the temperature of 200°C and pressure of 1200 atm. Thousands of … Read more

Chemical Properties of Alkenes Alkenes are chemically more reactive than alkanes. This because alkenes are unsaturated hydrocarbons that have a double bond, C=C, between two carbon atom. Almost all of the chemical reactions of alkene occur at the double bond. Alkenes can undergo: Combustion reaction Addition reaction Polymerisation reaction Combustion of Alkenes Like any other hydrocarbons, … Read more

Preparing Alkene Alkene can be prepared by dehydration of alcohol craking of alkane Dehydration of Alcohol When alcohol is heated, it will decompose to form alkene and water. For example, heating ethanol will produce ethene, heating propanol will produce propene, and so on. This process is called dehydration of alcohol. Dehydration of Ethanol  C2H5OH → C2H4 + … Read more

Physical Properties of the Alkenes Alkenes are covalent compounds that consist of simple molecules. The molecules of alkenes are held together by weak Van der Waals forces (intermolecular forces). As covalent compounds, the physical properties of alkenes are similar to alkanes. Boiling Points MUST Know!The first 3 alkenes are gases.The Melting and boiling point of … Read more

Isomerism of Alkenes All the alkenes with 4 or more carbon atoms in them show isomerism. For example, butene has 3 isomer: ExampleDraw the structural formulae for all 5 isomers of pentene.Answer:

General Formula: CnH2n, n = 2, 3, 4, …. Functional Group: Double Bond First 3 Members: Chemical Properties: MUST Know! Alkenes are unsaturated hydrocarbons. Alkenes are a family of hydrocarbons (compounds containing carbon and hydrogen only) containing a carbon-carbon double bond. Therefore, alkenes are unsaturated hydrocarbons. The general formula for alkene is CnH2n where n = … Read more

Isomerism Isomers are compounds with the same molecular formula but different structural formulae. Isomerism is the existence of two or more compounds that have the same molecular formula but different structural formulae.Examples of the two isomers of butane(The 2 molecules have same molecular formulae but different structural formulae) Isomers have different physical properties because they … Read more

A molecular formula is a chemical formula which shows the actual number of atoms of each element present in one molecule of a substance A structural formula is a chemical formula which shows the arrangement of the atoms in a molecule of a substance. Writing the Structural Formulae Rules to be followed: All atoms are … Read more

Chemical Properties of Alkanes Alkanes are chemically less reactive compared to the other carbon compound such as alkene, alcohol or carboxylic acid. Alkanes do not react with chemicals such as oxidizing agents, reducing agents, acids and alkalis. Alkanes are saturated hydrocarbon with strong carbon-carbon (C – C) bonds and carbon-hydrogen (C – H) bonds. All … Read more

Physical Properties of Alkanes Alkanes are covalent compounds, hence their physical properties are similar to other covalent compounds. The atoms in an alkane molecule are bonded together by strong covalent bonds  (intramolecular forces). The molecules are held together by weak Van der Waals forces (intermolecular forces). Boiling Points Boiling Point of Alkane The boiling point of alkane … Read more
