What are Hydrocarbons and which Classes of hydrocarbons are there? What are aromatic Hydrocarbons? We'll explain that to you in the following post.

Hydrocarbons explained simply

Hydrocarbons denote a group of substances which exclusively consist of Carbon and hydrogen atoms is composed. However, this group of substances is very diverse. Hydrocarbons can branched or ring-shaped his and also Double or triple bonds contain.

Hydrocarbons definition

The substance group of the Hydrocarbons are exclusively off Carbon and hydrogen atoms composed.

All hydrocarbon molecules are hydrophobic, are therefore not soluble in water. That I same in same dissolves, you can only dissolve a hydrocarbon in solvents that are also hydrophobic. Hydrocarbons come in particular in oil before and find as fossil fuels wide application possibilities.

Aliphatic hydrocarbons

As Aliphatic hydrocarbons you denote all hydrocarbons that are not aromatic. An aliphatic hydrocarbon can be either cyclical, so ring-shaped or acyclic, so don't be annular as well Multiple bonds have.

Saturated hydrocarbons

Let's take a look at those first saturated hydrocarbons at. A saturated hydrocarbon does not contain multiple bonds. You also will be Alkanes called and end by name -at. The simplest is hydrocarbon methane (CH4). Do you now add more CH to methane2-Groups, you get the homologous series the alkanes. The general form of the homologous series of alkanes is C.nH2n + 2.

If you would like to know more about the homologous series of alkanes, watch our video here.

The alkanes from the homologous series are all unbranched. If you look at alkanes from the homologous series, take them Boiling and melting points with increasing chain length to. Reason are Van der Waals forces, i.e. intermolecular interactions between the alkane chains. Ever longer the hydrocarbon chains are, the more greater is her surface for training Van der Waals forces.

Saturated hydrocarbons can also branched be. There are thus saturated hydrocarbons with the same Molecular formulabut more different Structural formula, also Structural isomers called. Your boiling and melting points decrease as the degree of branching increases from. You have with increasing degree of branching less contact area between the molecules and thus also low Van der Waals forces between the molecules.

Notice Van der Waals forces between hydrocarbons
  • Ever longer the hydrocarbon chain, the more greater are the Van der Waals forces
  • The more branched the molecule, the more less are the Van der Waals forces

Saturated hydrocarbons can also be e.g.yclic be. The smallest possible ring is Cyclopropene (C.3H6). Do you now add more CH2-Groups, you get the homologous series of cyclic hydrocarbons. The general formula for the homologous series of cyclic hydrocarbons is C.nH2n

The main representatives of the homologous series of cyclic hydrocarbons are
