Alkanes and alkenes

What is the reaction mechanism for the addition of bromine to an alkene? Does the mechanism change if the solvent is changed?

Alkanes and alkenes

What are the Uses of Alkanes and Alkenes? Alkanes are unreactive and are mainly used as fuels.

Organic Nomenclature - Alkanes. Other modules in this series: Nomenclature of Alkenes and Alkynes; Substitutional Organic Functional Groups. Special thanks to Vicki Winterton for providing the outline for this learning module. Alkenes and alkynes can be transformed into almost any other functional group you can name! We will review their nomenclature, and also learn about the vast possibility of reactions using alkenes and alkynes as starting materials. Discover the differences between alkanes and alkenes with BBC Bitesize GCSE Chemistry.

Alkenes are much more reactive than alkanes because alkenes are unsaturated they have a reactive double bond. Alkenes are the starting material for many different chemicals.

Educational videos for college students Reactions with halogens[ edit ] Main article:
What Is the Difference Between Alkane and Alkene? | r-bridal.com Alkanes, however, contain only single bonds between the carbons while alkenes contain at least one double bond between carbons.
Related Questions Reactions with halogens[ edit ] Main article: Free radical halogenation Alkanes react with halogens in a so-called free radical halogenation reaction.
Alkene - Wikipedia Industrial methods[ edit ] Alkenes are produced by hydrocarbon cracking.

They are extremely useful to the chemical industry. Ethene and propene are the starting materials for polymers, giving poly ethene and poly propene - see polymers. How to Tell an Alkane from an Alkene? An alkene may be distinguished from an alkane by shaking the hydrocarbon with bromine water.

Bromine water is brown or orange, and will lose its colour when it reacts with the double bond of an alkene. Bromine water will stay brown with an alkane because an alkane has no double bonds. Bromine adds across the double bond of an alkene to form a colourless dibromo alkane.

This is an example of an addition reaction. What is an Addition Reaction? An addition reaction occurs when two or more reactants join together to form a single product. Other examples of addition reactions are.Part ALKANES.

Introduction to alkane reactivity. Alkanes are not very reactive r-bridal.com reactions require some energy input to initiate a reaction e.g.

high temperature and catalyst for cracking, uv light for chlorination or a spark to ignite them (initiating free radical reactions).; A combination of two main reasons account for this lack of reactivity compared to most other. Revision Questions for Fossil Fuels, Crude Oil, Hydrocarbons, Alkanes, Alkenes, Cycloalkanes, Isomers and Combustion.

Powerpoint and Afl task for teaching alkanes and alkenes. Goes well with my other resource - hydrocrbon bingo. Alkenes & Alkenes Homologous Series.

Alkanes and alkenes

Alkenes are referred to as unsaturated molecules. This means they contain at least one carbon-carbon double bond which displaces two hydrogen atoms and thus, alkenes do not have the maximum number of hydrogen atoms per carbon atom.

All Mechanisms: Displaying mechanisms: Alicyclic- electrophilic addition of bromine to cyclohexene (bromonium ion opening) Alicyclic- Grobb rearrangement. Alkanes and alkenes are both hydrocarbons.

Alkanes, however, contain only single bonds between the carbons while alkenes contain at least one double bond between carbons.
