Saturated and Unsaturated Hydrocarbons

There are four bonds for each carbon atom in alkane C- H or C- C bond are possible one. Contain fewer hydrogens than the corresponding saturated hydrocarbons.

The molecular formulas of these unsaturated hydrocarbons reflect the multiple bonding of the functional groups.

. Alkanes hydrocarbons in which all the bonds are single have molecular formulas that satisfy the general expression C n H 2n 2 where n is an integer. For a branched unsaturated acyclic hydrocarbon the parent chain is the longest carbon chain that contains the maximum number of double and triple bonds. Saturated hydrocarbons contain carbon-carbon and carbon-hydrogen single bonds.

Alkenes are unsaturated. Unsaturated hydrocarbons are hydrocarbons that have double or triple covalent bonds between adjacent carbon atomsThe term unsaturated means more hydrogen atoms may be added to the hydrocarbon to make it saturated ie. Main groups of hydrocarbons.

Polymeric isoprenoid hydrocarbons have also been identified. C n H 2n2. Alkanes and cycloalkanes are termed saturated.

Fatty acids are long chain hydrocarbons with carboxyl groups COOH groups. Z16 gases petroleum C 3-C 4 isobutane-rich a complex combination of hydrocarbons - obtained from the distillation of saturated and unsaturated hydrocarbons having carbon numbers predominantly in the range of C 3 through C 6 predominantly butane and isobutane - consisting of saturated and unsaturated hydrocarbons having carbon numbers. These fatty acids can be classified into saturated or unsaturated based on the number of double bonds present in the fatty acid.

The general representation of alkane is C n H 2n2 in case of non-cyclic structures. Contain more hydrogen atoms than the corresponding unsaturated hydrocarbons. The liquid and gaseous phases of petroleum constitute the most important.

Ii unsaturated and iii aromatic hydrocarbons. Alkanes are saturated hydrocarbons means they formed by a single bond in between the carbon atoms. Unsaturated hydrocarbons are alkenes and alkynes which have one carbon-carbon double bond and one carbon-carbon triple bond respectively.

Properties of Aliphatic Hydrocarbons. It is subtracted in the formula to count how many pairs of hydrogen atoms are missing in the unsaturated structure which tells us the degree of hydrogen deficiency. The term is often restricted to the liquid form commonly called crude oil but as a technical term petroleum also refers to natural gas and the viscous or solid form known as bitumen which is found in tar sands.

Alkanes and alkenes both form homologous series of hydrocarbons but. An unsaturated hydrocarbon that contains at least one carboncarbon double bond with the general formula C n H 2n. An organic compound consisting entirely of hydrogen and carbon.

The simplest aliphatic hydrocarbon is methane CH 4. Alkanes - saturated hydrocarbons The names of the straight chain saturated hydrocarbons for up to a 12 carbon chain are shown below. In addition to hydrogen other elements may be bound to the carbon atoms in the chain including oxygen nitrogen chlorine and sulfur.

The double bonds in the unsaturated compounds listed on the right are all cis or Z. Petroleum complex mixture of hydrocarbons that occur in Earth in liquid gaseous or solid form. R-CH 2-CH 2-R.

For hydrocarbons the DBE or IHD tells us the number of rings andor extra bonds in a non-saturated structure. This is the maximum HC ratio for a given number of carbon atoms. An acyclic saturated hydrocarbon with the general formula C n H 2n2Also called paraffin.

Alkynes are also unsaturated hydrocarbon carbons like same as. The configuration of an unsaturated carbons include straight chain such as alkenes and alkynes as well as branched. On the other hand if carbon atoms.

No hydrogen pair is missing if IHD 0 which corresponds to. Aliphatic compounds may be saturated eg hexane and other alkanes or unsaturated eg hexene and other alkenes as well as alkynes. If different carbon atoms are joined together to form open chain of carbon atoms with single bonds they are termed as alkanes as you have already studied in Unit 12.

Saturated fatty acids contain only single bond between the carbon atoms and are tend to be solids at room temperature. They contain sp 2 or sp hybridized carbons. All carbon atoms are sp 3 hybridized in these compounds.

Consisting all single bonds. Natural fatty acids may be saturated or unsaturated and as the following data indicate the saturated acids have higher melting points than unsaturated acids of corresponding size. Alkanes are described as saturated hydrocarbons while alkenes alkynes and aromatic hydrocarbons are said to be unsaturated.

Alkanes are saturated their carbon atoms are only joined by C-C single bonds. If there are two or more chains competing for selection. Definitions of organic compounds.

Unsaturated hydrocarbons are more reactive than saturated hydrocarbons and usually fewer hydrogen atoms can be seen in bonds with carbon atoms. Examples include alkanes and cycloalkanes.
