Nomenclature of Alkynes Nomenclature of Alkynes. Alkynes are organic molecules made of the functional group carbon-carbon triple bonds and are written in the empirical formula of \(C_nH_{2n-2}\). They are unsaturated hydrocarbons. Like alkenes have the suffix –ene, alkynes use the ending –yne; this suffix is used when there is only one alkyne in the molecule.

Organic Chemistry/Alkenes Alkenes are molecules with carbons bonded to hydrogens which contain at least two sp 2 hybridized carbon atoms. That is, to say, at least one carbon-to-carbon double bond, where the carbon atoms, in addition to an electron pair shared in a sigma (σ) bond, share one pair of electrons in a pi (π) bond between them.aming Alkenes [edit]. Alkenes are named as if they were alkanes, but the -ane suffix is changed to -ene. If the alkene contains only one double bond and that double bond is terminal (the double bond is at one end of the molecule or another) then it is not necessary to place any number in front of the name.

- The products of cracking include alkenes (for example ethene and propene). The alkenes are a family of hydrocarbons that share the same general formula. This is C n H 2n. The general formula means that the number of hydrogen atoms in an alkene is double the number of carbon atoms.he presence of this double bond allows alkenes to react in ways that alkanes cannot. They can react with oxygen in the air, so they could be used as fuels. But they are more useful than that. They can be used to make ethanol-alcohol-and polymers-plastics-two crucial products in today's world. Page: 1  1.

- The general formula of an alkene is CnH2n. An alkyne is a hydrocarbon containing triple bonds. The general formula of an alkyne is CnH2n-2. The term saturated is used to refer to a compound in which all carbon-carbon bonds are single bonds and every carbon atom is connected to a different atom.

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.

Organic Chemistry/Alkynes Organic Chemistry/Alkynes. < Organic Chemistry. The triple carbon bonds is formed in alkynes, due to the absence of hydrogens, thus allowing carbon bonds to become stronger, due to the nucleus central force which pulls in nearby atoms. << Alkenes |Alkynes| Dienes >>. Alkynes are hydrocarbons containing carbon-carbon triple bond.

Unsaturated Hydrocarbon: Definition & Examples There are three types of unsaturated hydrocarbons: alkenes, alkynes and aromatic hydrocarbons. Alkenes are unsaturated hydrocarbons that have one or more carbon-carbon double bond, with a general structure of (R-C=C-R'), where R and R' are hydrocarbon groups attached to either side of the carbon atoms.

Unsaturated Hydrocarbon: Definition & Examples Alkynes are unsaturated hydrocarbons that have one or more carbon-carbon triple bonds. When naming alkynes, the suffix 'yne' is used, which notifies us that there is a triple bond present in the compound.

Alkane Types and Structures Alkanes contain only single bonds, which means they are saturated with hydrogen atoms. They are the basic hydrocarbons and the starting points for understanding the chemistry of other, more complex molecules. Alkanes get their name from the alkyl group that is composed of a carbon and three hydrogens.

- 21 Experiment 5 – Reactions of Hydrocarbons Hydrocarbons are compounds that only contain carbon and hydrogen. Hydrocarbons can be classified further by the type of bonds they contain. If a hydrocarbon contains only single bonds, it is an alkane.If it contains one or more carbon-carbon double bonds, it is classified as an alkene. If it contains one or more triple bonds between two carbon atoms, it is an alkyne.herefore, alkanes, alkenes, and alkynes are all aliphatic hydrocarbons.) These types of compounds react in different ways, so it is possible to distinguish between them using experimental tests. Physical Properties Since hydrocarbons contain only carbon and hydrogen, all hydrocarbons are nonpolar.

- Alkyl group. Definition: An alkyl is a functional group of an organic chemical that contains only carbon and hydrogen atoms, which are arranged in a chain. They have general formula C n H 2n+1. Examples include methyl CH 3 (derived from methane) and butyl C 2 H 5 (derived from butane).n alkyl is a functional group of an organic chemical that contains only carbon and hydrogen atoms, which are arranged in a chain. They have general formula C n H 2n+1.

- Hydrocarbons: Alkenes Alkenes are unsaturated hydroacrbons – that is they contain one or more C=C double bonds.General formula: straight chain alkenes with one C=C bond form an homologous series with the general formula C n H 2n .Structure of alkenes:Ethene is a flat planar molecule.

This page Double-bonded carbons are sp 2 -hybridized, and have trigonal planar shapes, with the bonded atoms at angles of 120 to each other. Free rotation is not possible around carbon-carbon double bonds in alkenes, making the carbon chains less flexible and floppy than those of alkanes with the same number of carbons.heir 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. Alkenes take part in a wide variety of chemical reactions, and are found as parts of many highly colored systems (see below for examples).

Alkynes The 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.

Organic Chemistry Alkenes have the general formula C n H 2n, and are examples of unsaturated hydrocarbons. The presence of a double bond compound's structure causes there to be two fewer hydrogen atoms in the molecule than there are in an alkane with the same number of carbon atoms.

Difference Between Alkanes, Alkenes and Alkynes Alkanes, Alkenes vs Alkynes. Alkanes, alkenes and alkynes are all hydrocarbons with different structures and thus different physical and chemical properties. Hydrocarbons. In the study of organic chemistry, the organic compounds which are made up of carbon and hydrogen are called hydrocarbons.lkanes are saturated hydrocarbons which mean they are compounds with a single bond between the atoms. Saturated hydrocarbons are saturated with hydrogen and are the simplest. They are represented in general as CnH2n+2 in case of non-cyclic structures or straight-chain structures. They are also called paraffins.

Alkane An alkyl group, generally abbreviated with the symbol R, is a functional group or side-chain that, like an alkane, consists solely of single-bonded carbon and hydrogen atoms, for example a methyl or ethyl group.he simplest isomer of an alkane is the one in which the carbon atoms are arranged in a single chain with no branches. This isomer is sometimes called the n-isomer (n for normal, although it is not necessarily the most common).
