What Is An Alkene

The words alkene and olefin are often used interchangeably see nomenclature section below. Alkenes are a class of hydrocarbons e g containing only carbon and hydrogen unsaturated compounds with at least one carbon to carbon double bond.

Predict the molecular formula of decene and explain your answer.

What is an alkene. The ene suffix ending indicates an alkene or cycloalkene. The longest chain chosen for the root name must include both carbon atoms of the double bond. Alkenes are more reactive than alkanes due to the presence of the double bond.

Decene is an alkene. Alkenes are unsaturated hydrocarbons having the chemical formula c n h 2n. They re characterised by a covalent carbon carbon double bond.

Alkenes are one of the most important useful molecular families in all of organic chemistry. Alkenes also known as olefins are organic compounds that consist of carbon and hydrogen atoms with one or more carbon carbon double bonds in their chemical structure. Iupac rules for alkene nomenclature.

Another term used to describe alkenes is olefins. Alkene definition is any of numerous unsaturated hydrocarbons having one double bond. A two carbon alkene therefore is named ethene.

A three carbon alkene is named propene and an alkene in a five membered ring is. These are called hydrocarbons because alkenes are only composed of c and h atoms. The formula will be c10h20.

They are called unsaturated because they are composed of at least one c c double bond. Any of a series of open chain hydrocarbons cnh2n such as ethylene. In organic chemistry an alkene is an unsaturated hydrocarbon that contains a carbon carbon double bond.

Therefore there cannot be any alkene having only one carbon atom. Its molecules contain 10 carbon atoms. Whereas the names of alkanes end with the suffix ane alkenes end with the suffix ene.

If you know how to name alkanes adding alkene nomenclature to your repertoire is a fairly straightforward task. The root chain must be numbered from the end nearest a double bond carbon atom if the double bond is in the center of the chain the nearest substituent rule is used to determine the end where numbering. Unsaturated hydrocarbons containing two or more double bonds are known as alkadienes alkatrienes alkatetraenes and so on.
