Alkanes and alkenes complete combustion needs plenty of air alkanes and alkenes are both families of hydrocarbons alkanes are useful as fuels and alkenes are used to make chemicals such as plastic. Alkanes are saturated hydrocarbons a saturated hydrocarbon (alkane) contains only single c-c covalent bonds, whereas an unsaturated hydrocarbon (alkene or alkyne) contains at least one c=c or c≡c bond. Alkanes have single bonds, alkenes contain a carbon-carbon double bond, and alkynes have a carbon-carbon triple bond also, alkanes are labelled as saturated hydrocarbons, while alkenes, alkynes, and aromatic hydrocarbons are said to be unsaturated.
Branched and unbranched alkenes ( isomerism in alkenes): they have the same molecular formula c 4 h 8 , but have different structural formula butene is a straight-chain unsaturated hydrocarbon while methylpropen is a branched-chain, unsaturated hydrocarbon. Alkanes are long chains of carbons linked together by a single bond, and are also known as paraffin's 2-5% alkenes, which are hydrocarbons containing at least one carbon-to-carbon double bond alkenes are commonly referred to as olefins 25-40 % isoalkanes, similar to alkanes, isoalkanes are also paraffin's. Alkenes are more reactive than alkanes due to the c=c bond types of reactions that alkene undergo is called addition (with bromide water) - ethene + bromine water → 1,2 dibromo ethane.
Chemistry- alkanes and alkenes the process of naming compounds allows chemists to communicate formulae in words rather than in chemical symbols there are, however, a few rules about naming compounds which need to be known in order to write a formula in word form or translate a compound in word form into chemical symbols. I was taught that alkanes, alkenes and alkynes were all hydrocarbons, ie consisted only of carbon and hydrogen (so no oxygen, chlorine or flourine), and our definition of an alkane was exactly the one currently in the alkane article but that was a long time ago. Alkanes, alkenes, and alkynes are organic compounds called hydrocarbons this experiment was performed to determine the differences in the properties of alkanes, alkenes and alkynes through its representative compounds butane, ethylene and acetylene. Alkanes are much more stable than alkenes because of the presence of the c=c double bond the old name for the alkanes was the paraffins alkynes may have one or more triple bonds in their structure. Alkanes, alkenes, and alkynes are all organic hydrocarbons an organic molecule is one in which there is at least one atom of carbon, while a hydrocarbon is a molecule which only contain the atoms hydrogen and carbon many of these molecules are used in the production of other materials, such as.

Alkanes, alkenes and alkynes a hydrocarbon that contains no double bonds is called an alkane , or hydrocarbon containing only single bonds methane and ethane are both alkanes.
Alkanes, alkenes and alkynes are simple hydrocarbon chains with no functional groups the simplest organic compounds are the alkanes alkanes have only single bonds between carbon atoms and are called saturated hydrocarbons. Introduction to alkanes, alkenes, alkynes and alcohols: alkanes are hydrocarbons with only single bonds between the atoms it can be either straight-chain or branched-chain straight-chain alkanes are the simplest alkenes are molecules that have a carbon-carbon double bond alkynes are molecules. Alkenes are industrially useful molecules and smaller alkanes are used in fuels such as petrol thermal cracking: high temperatures (typically in the range of 450°c to 750°c) and pressures (up to about 70 atmospheres) are used to break the large hydrocarbons into smaller ones.
Simple alkenes are named like alkanes (root from the longest carbon chain), but the -ane suffix is replaced by-ene h2c ch2 ethene h2c chch3 propene cyclohexene when the chain is longer than 3 carbons, number the atoms such that the double bond is given the lowest number (ie start at the end nearest the double bond. The original mixture of a colourless and a green gas would produce steamy fumes of hydrogen chloride and a mist of organic liquids all of the organic products are liquid at room temperature with the exception of the chloromethane which is a gas. I'm thinking that kerosene must be an alkane because it is saturated with no double bonds and it's formula is c10h22 however why does it end in ene not. Alkene reactions are the foundation for all future organic chemistry reactions and mechanisms to help you build that solid foundation i've put together this short quiz testing your knowledge of reactions, reagents, products and additional molecule concepts.
