Saturated vs. Unsaturated Hydrocarbons 1. Alkanes-Are saturated hydrocarbons that therefore contain only hydrogen and carbon atoms bonded to each other, and typically follow the chemical formula C n H 2n+2. A common example is paraffin. 2. Alkenes-These unsaturated hydrocarbons are molecules that contain at least one carbon-to-carbon double bond.

Alkanes 1 Alkanes are Saturated Hydrocarbons. 2  They consist of the elements Carbon and Hydrogen, and all the bonds between the Carbon atoms are single bonds. 3  They have the general formula CnH2n+2.4  Since all Alkanes are similar in structure and properties, they are called a Homologous Series. Alkanes are Saturated Hydrocarbons. 2  They consist of the elements Carbon and Hydrogen, and all the bonds between the Carbon atoms are single bonds. 3  They have the general formula CnH2n+2.

- (aka ALKANES). An Unsaturated Compound contain one double covalent bond between carbon atoms or a triple covalent bond between carbon atoms. the bonds of carbon are not fully utilised by hydrogen atoms, more of these can be attached to them.

Alkynes Alkynes. The alkynes are the third homologous series of organic compounds of hydrogen and carbon, where there is at least one triple-bond between the atoms in the molecules.The alkenes are said to be unsaturated because of the existence of a multiple bond in the molecule.he carbon-carbon triple bond of the alkynes is formed in the same way as a double bond of the alkenes, by the elimination of atoms or groups from two adjacent carbons.

- Unsaturated hydrocarbon: a hydrocarbon that contains one or more carbon-carbon double bonds, triple bonds, or benzene rings. Alkanes: They are saturated hydrocarbons (they have only carbon-carbon single bonds). The molecular formula of this group is C n H 2n+2 (n is the number of carbon atoms). Naming the unbranched alkanes: Chemists have adopted a set of rules established by the International Union of Pure and Applied Chemistry (IUPAC). The IUPAC name for an alkane consists of two parts: 1.

Alkanes Alkanes. Hydrocarbons which contain only single bonds are called alkanes. They are called saturated hydrocarbons because there is a hydrogen in every possible location. This gives them a general formula C n H 2n+2.The first four alkanes are methane, ethane, propane, and butane with the Lewis symbols shown below.Past this number of carbons, the-ane suffix is retained and the number prefixes penta-, hexa-, hept-, oct-, non-, dec-, etc are used.his gives them a general formula C n H 2n+2.

- Alkanes are relatively small molecules in which all the chemical bonds are covalent bonds. All the bonds in alkane molecules are single bonds i.e. C C carbon carbon or C H carbon hydrogen. Each carbon atom forms four single covalent bonds and hydrogen atoms form one single covalent bond. All single bonds are formed by sharing a pair of electrons e.g. one from each of a carbon atom and a hydrogen atom, or two carbon atoms contributing (sharing) an electron each to the covalent bond.

- Alkanes. Crude oil forms naturally over millions of years from the remains of living things. Most of the compounds in crude oil are hydrocarbons. These are compounds that contain hydrogen and carbon atoms only, joined together by chemical bonds called covalent bonds.he alkanes are a family of hydrocarbons that share the same general formula. This is: CnH2n+2. The general formula means that the number of hydrogen atoms in an alkane is double the number of carbon atoms, plus two.

olefin Alkenes are relatively stable compounds, but are more reactive than alkanes, either because of the reactivity of the carbon–carbon pi-bond or the presence of allylic CH centers. Most reactions of alkenes involve additions to this pi bond, forming new single bonds.cyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula C n H 2n. Alkenes have two hydrogen atoms less than the corresponding alkane (with the same number of carbon atoms).

- Alkenes. Alkenes are hydrocarbons which contain carbon-carbon double bonds. Their general formula is C n H 2n for molecules with one double bond (and no rings). Alkenes are also known as olefins, after the original name for ethene, olefiant gas.

olefin In organic chemistry, an alkene is an unsaturated hydrocarbon that contains at least one carbon –carbon double bond. Alkene, olefin, and olefine are used often interchangeably (see nomenclature section below).Acyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula C n H 2n.Alkenes have two hydrogen atoms less than the corresponding alkane (with the same number of carbon atoms).cyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula C n H 2n.

- Alkanes are unreactive and are mainly used as fuels. 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.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.n 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.

- Straight-chain alkanes are named by using a stem that indicates the number of carbon atoms (meth = 1 C, eth = 2 C's, prop = 3 C's, etc.) to which is added the suffix-ane, indicating that the molecule is an alkane (that is, that the carbon atoms are all connected by single bonds).ree rotation is possible around the carbon-carbon single bonds in alkanes, making the carbon chains very flexible and floppy — particularly for the larger molecules. Alkanes are nonpolar molecules, since they contain only nonpolar carbon-carbon and carbon-hydrogen bonds.

What are Alkyl groups? An alkyl group is a univalent radical consisting of carbon and hydrogen atoms, with one H atom less than their alkane counterparts. They form homologous series with a general formula of CnH2n+1, while the general formula of the alkanes is CnH2n+2.est Answer: Alkyl groups are substituents that have one less H (hydrogen atom) than the corresponding alkane.

Alkane In organic chemistry, an alkane, or paraffin (a historical name that also has other meanings), is an acyclic saturated hydrocarbon. In other words, an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon-carbon bonds are single.
