Alkenes

Share View PDF | Print View | Views: 1040 |

The general formula for alkenes is as follows:

C_nH_2n   (where "n" is a constant)

Alkenes are unsaturated hydrocarbons because they contain a double bond between two of their carbon atoms. The simplest alkene is ethene (C₂H₄) because "methene" (CH₂) cannot exist.

The first four members of the homologous series of the alkenes are:

C₂H₄     (Ethene - Gas at room temperature/pressure)
C₃H₆     (Propene - Gas at room temperature/pressure)
C₄H₈     (Butene - Gas at room temperature/pressure)
C₅H₁₀     (Pentene - Liquid at room temperature/pressure)
