- in chemical compound: Alkynes. Molecules that contain a triple bond between two carbon atoms are known as alkynes. The triple bond is made up of one σ bond and two π bonds. As in alkenes, the π bonds constitute regions of increased electron density lying parallel to the carbon-carbon bond axis.

Organic Chemistry/Alkenes/Cycloalkenes Organic Chemistry/Alkenes/Cycloalkenes - Cycloalkenes. 1  A cycloalkene (also sometimes called a cycloolefin) is a type of alkene hydrocarbon which contains a closed ring of carbon atoms. The prefix cyclo- comes from ancient Greek and in this case means round.

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.

Difference Between Alkanes, Alkenes and Alkynes 1.Alkanes are saturated hydrocarbons; meaning a single bond between the carbon atoms; alkenes are unsaturated hydrocarbons meaning one or more double bonds between carbon atoms; alkynes are also unsaturated hydrocarbons with one or more triple bonds between the carbon atoms.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.

Trench Talk â about non-muscle-invasive bladder cancer Underarm hair also usually shows up near the end of puberty. The whole process usually takes about two and a half to three years, but it can take up to four or five years. If these things start happening at age 7 or 8, that may seem too soon to you, but it's within the range of normal.

Alkylation is an important source for octane in gasoline Alkylation is an important source for octane in gasoline. Source: Occupational Safety and Health Administration. Alkylation (al-kuh-ley-shun) is a secondary refinery unit operation that many refineries in the United States have because it adds high octane hydrocarbons to motor and aviation gasoline. High octane hydrocarbons are needed to help prevent autoignition of gasoline (knocking) in an engine and to meet recommended engine octane ratings.

Alkanes Alkanes are saturated hydrocarbons. This means that their carbon atoms are joined to each other by single bonds. This makes them relatively unreactive, apart from burning or combustion, which is their reaction with oxygen in the air.

- Alkynes are organic unsaturated hydrocarbons that have carbon-carbon triple bonds in their chemical structure. The general formula for alkynes is RCCR', where R and R' are side groups of carbon and/or hydrogen atoms bonded together.

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.he simplest alkene, ethylene (C 2 H 4), which has the International Union of Pure and Applied Chemistry (IUPAC) name ethene is the organic compound produced on the largest scale industrially.

- 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.

Ketone In chemistry, a ketone (alkanone) /ˈkiːtoʊn/ is an organic compound with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents. Ketones and aldehydes are simple compounds that contain a carbonyl group (a carbon-oxygen double bond). They are considered simple because they do not have reactive groups like −OH or −Cl attached directly to the carbon atom in the carbonyl group, as in carboxylic acids containing −COOH.

Alkanes Alkanes are hydrocarbons in which the carbon atoms are held together by single bonds. Their general formula is C n H 2n+2 for molecules which do not contain ring structures.traight-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).

Heptane Application: n-Heptane is a straight-chain alkane consisting of seven carbons that is widely used as a completely non-polar solvent. n-Heptane is sometimes chosen as a less toxic option to the traditional hexane in appropriate processes. In liquid form, n-Heptane is very easy to transport and store.

Unsaturated hydrocarbon (December 2009). Unsaturated hydrocarbons are hydrocarbons that have double or triple covalent bonds between adjacent carbon atoms. Those with at least one carbon to carbon double bond are called alkenes and those with at least one carbon to carbon triple bond are called alkynes.xcept for aromatic compounds, unsaturated hydrocarbons are highly reactive and undergo addition reactions to their multiple bonds. Typical reagents added are hydrogen halides, water, sulfuric acid, elemental halogens and alcohols.

What is Ethane? Ethane is a hydrocarbon compound that exists in nature as an odorless and colorless gas at standard temperature and pressure. Due to the presence of a single bond in its structure, it is classified as an alkane hydrocarbon and is included in the first four primary alkanes: methane, ethane, propane, and butane.
