homologous series of hydrocarbons that contain a carbon-carbon double bond. The number of hydrogen atoms in an alkene is double the number of carbon atoms, so they have the general formula CnH2n.

All the alkenes with 4 or more carbon atoms in them show structural

The carbon-carbon double bond doesn't allow any rotation about it, (cis-trans isomerism).

Shared electrons in the double bond are called pi electrons and they create a pi bond.

The electrons in the pi bond are free to move around anywhere in this shaded region and can move freely from one half to the other.

The rather exposed electrons in the pi bond are particularly open to attack by things which carry some degree of positive charge. These are called

Alkenes are a of that contain a carbon-carbon double bond. The number of hydrogen in an alkene is double the number of carbon atoms, so they have the general formula \(C_{n}H_{2n}\) .

For example, the molecular formula of ethene is \(C_{2}H_{4}\) , while for propene it is \(C_{3}H_{6}\) .

Here are the names and structures of four alkenes:
