Alkenes

• Alkenes


  Contain at least one carbon-carbon double bond
• Alkenes

  • a.k.a. olefins
  • Classified as unsaturated hydrocarbons
  • suffix: -ene
• The general formula for an alkene with n carbons is CnH2n.
• Geometric Isomers

  • Compounds which describes certain arrangements of atoms within molecules.
  • Also known as cis-trans isomerism

  
• Cis-isomer


  Two particular atoms or group of atoms are adjacent to each other

  
• Reactions of Alkenes


  Hydrogenation
• Hydrogenation

  Addition reaction; two hydrogen atoms are added across the double bond of an alkene, resulting in a saturated alkane.

  A) Alkene to alkane

  
• Trans-isomer


  Two groups are across each other
