Topic: List of alkanes


  
  Alkanes
A normal hydrocarbon alkane is one where all the carbon atoms in the molecule are in a "continuous" chain.
Use the normal alkane name corresponding to the number of carbons in the continuous chain and attach it to the first part of the name.
Alkanes are insoluble in water because the polar water molecules are not attracted to the non-polar alkane molecules.

  Alkane - Wikipedia, the free encyclopedia
An alkane in organic chemistry is a saturated hydrocarbon without cycles, that is, an acyclic hydrocarbon in which the molecule has the maximum possible number of hydrogen atoms and so has no double bonds.
Alkanes are also often known as paraffins, or collectively as the paraffin series; these terms, however, are also used to apply only to alkanes whose carbon atoms form a single, unbranched chain; when this is done, branched-chain alkanes are called isoparaffins.
Alkanes have a low reactivity because the C-H and C-C single bonds are relatively stable, difficult to break and non-polar.

An alkane in organic chemistry is a type of hydrocarbon in which the molecule has the maximum possible number of hydrogen atoms and so has no double bonds (they are saturated).
The alkanes, and their derivatives, with four or fewer carbons have non-systematic common names, established by long precedence.
Alkanes have a low reactivity because the C-H and C-C single bonds are relatively stable and difficult to break.

 Alkanes
Alkanes with higher values of n are found in diesel fuel, fuel oil, petroleum jelly, paraffin wax, motor oils, and for the highest values of n, asphalt.
Alkane derivatives are used in hundreds of products such as plastics, paints, drugs, cosmetics, detergents, insedticides, etc., so the fossil fuel resource from which we obtain the alkanes is much too valuable to burn it all as a motor fuel.
Alkane derivatives can be formed by substituting an alkyl group for one of the hydrogens.

Compare this with the energy released when 1g of each of the alkanes, methane and ethane (see data on the spreadsheet or plot this as the current set of data) are completely burned and explain why hydrogen is not used more widely as a fuel.

One commenter believes that listing broad categories where the individual members have diverse properties and cause diverse effects does not constitute ``good science.'' The Agency agrees that a category must be rationally constructed both in terms of similarity in the properties of the individual members and in terms of their effects.
By listing chemicals that present a hazard and providing TRI data on these chemicals to the public, EPA allows the public to make the determination as to whether there is a risk in their community.
The EPCRA section 313(d)(2) listing criteria each state that EPA may list a chemical that it determines ``causes or may reasonably be anticipated to cause'' the relevant adverse human health or environmental effects.

 Alkanes
Alkanes are the simplest organic molecules, they only contain C and hydrogen, and only contain single bonds.
Alkanes are non-polar, and are said to be Hydrophobic (‘water hating’) since they do not dissolve in water.
Shorter chain alkanes are obtained commercially by the ‘catalytic cracking’ of larger chain alkanes such as crude oil or petroleum refining.
