Acyclic unsaturated hydrocarbons containing a carbon-carbon double bond are called alkenes. They are also called olefins since the lower members of this class produce oily products on reaction with halogens such as chlorine and bromine. Structures of Double Bond The carbon-carbon double bond in alkenes consists of one strong carbon-carbon σ-bond with a bond dissociation … [Read more...] about Alkenes

Alkanes
Hydrocarbons are divided into two types: (1) Acyclic or open chain hydrocarbons (2) Cyclic or closed chain hydrocarbons Acyclic or open chain hydrocarbons These compounds contain open chains of carbon atom in their molecules. They are also called aliphatic hydrocarbons. These are further classified into following three categories : (1) Alkanes : An alkane has only … [Read more...] about Alkanes
Stereoisomerism
Isomers which have same structural formula but have different relative arrangement or atoms or groups in space are called stereoisomers and the phenomenon is called stereoisomerism. cis-trans isomerism is an example of stereoisomerism. Due to π-bonding between the two carbon atoms, the rotation around carbon-carbon double bond is prohibited and hence the geometry of … [Read more...] about Stereoisomerism
