Alkenes

Alkenes

  • General formula - CnH2n

  • Features of alkenes

    • At least one C=C bond

    • Double bond makes them unsaturated

  • Examples of alkenes

    • Ethene (C2H4)

    • Propene (C3H6)

Shapes of Alkenes

  • Trigonal planar shape due to equal repulsion of electrons

  • 120° bond angles

  • E.G. Ethene

Reactivity of Alkenes

  • More reactive than Alkenes

  • The high electron density of the C=C bond allows them to attract electrophiles
