What are alkanes , alkenes and alkynes ?

Answered by Expert
  • Alkanes are hydrocarbons in which all the linkages between the carbon atoms are single covalent bonds.
  • Compounds are known as saturated hydrocarbons because all the four valencies of carbon are fully satisfied.
  • General formula of alkanes: CnH2n+2


  • Alkenes are unsaturated aliphatic hydrocarbons containing a carbon–carbon double bond.
  • They are also called olefins because of their tendency to form oily products.
  • General formula of alkenes: CnH2n


  • Alkynes are unsaturated aliphatic hydrocarbons containing a carbon–carbon triple bond in their molecule.
  • The general formula of alkynes is CnH2n−2.
  • More reactive than alkenes because of the presence of a triple bond, often referred to as an acetylenic linkage.
