Most reactions of organic compounds take place at or adjacent to a functional group. In order to establish a baseline of behavior against which these reactions may be ranked, we need to investigate the reactivity of compounds lacking any functional groups. Such compounds are necessarily hydrocarbons , made up of chains and rings of carbon atoms bonded to a full complement of hydrogen atoms all carbons are sp 3 hybridized.

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. Alkenes have at least one carbon-carbon double bond. Alkynes have one or more carbon-carbon triple bonds. Alkenes and alkynes are called as unsaturated hydrocarbons.

Alkenes have the general formula C n H 2n. The general formula for alkynes is C n H 2n Acetylene is the simplest alkyne with the formula as C 2 H 2. Alkanes are non-polar compounds and insoluble in water. They have low boiling and melting points.

Natural gas, camping gas, lighter gas and much of gasoline are all alkanes. All the alkanes burn but they need a lot of air or oxygen to burn completely.

Alkenes and alkynes are more reactive than alkanes. Keep your current shopping and add the saved Cart? Remove your current shopping cart and replace with the saved cart?

The largest database 1 of organic compounds lists about 10 million substances, which include compounds originating from living organisms and those synthesized by chemists. The number of potential organic compounds has been estimated 2 at 10 60 —an astronomically high number. The existence of so many organic molecules is a consequence of the ability of carbon atoms to form up to four strong bonds to other carbon atoms, resulting in chains and rings of many different sizes, shapes, and complexities. The simplest organic compounds contain only the elements carbon and hydrogen, and are called hydrocarbons. Even though they are composed of only two types of atoms, there is a wide variety of hydrocarbons because they may consist of varying lengths of chains, branched chains, and rings of carbon atoms, or combinations of these structures. In addition, hydrocarbons may differ in the types of carbon-carbon bonds present in their molecules. Many hydrocarbons are found in plants, animals, and their fossils; other hydrocarbons have been prepared in the laboratory.


Cis-Trans Nomenclature. E-Z Nomenclature. 28 As a result of the double or triple bond nature, alkenes and alkynes have fewer hydrogen atoms The physical properties of alkenes are similar to those of the alkanes. Table shows.


Nomenclature of Alkenes

In order to name organic compounds you must first memorize a few basic names. These names are listed within the discussion of naming alkanes. In general, the base part of the name reflects the number of carbons in what you have assigned to be the parent chain. The suffix of the name reflects the type s of functional group s present on or within the parent chain.

The molecular formula of a hydrocarbon provides information about the possible structural types it may represent. This difference suggests such compounds may have a triple bond, two double bonds, a ring plus a double bond, or two rings. Some examples are shown here, and there are at least fourteen others! Hence, as with alkanes, a consistent nomenclature system needs to be adopted that can separate the nature of these unsaturated chemicals.

These effects depend on the size of the hydrocarbon molecules and where on or in the body they are applied.

In organic chemistry , an alkane , or paraffin a historical trivial 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. However, some sources use the term to denote any saturated hydrocarbon, including those that are either monocyclic i. In an alkane, each carbon atom is sp 3 -hybridized with 4 sigma bonds either C—C or C—H , and each hydrogen atom is joined to one of the carbon atoms in a C—H bond. The longest series of linked carbon atoms in a molecule is known as its carbon skeleton or carbon backbone.
