Presentation Transcript

  1. Other aliphatic hydrocarbons

  2. Objectives

  3. Rules

  4. Unsaturated

  5. Alkenes I certainly learnt to call ethylene ethene and propylene propene (see slide 1)

  6. Molecular formula • Alkanes • CnH2n+2 • Alkenes • CnH2n • Alkynes? • What are the formulae of • Pentane • Hexene • Octene • Nonane

  7. isomers

  8. Alkenes

  9. Cis and trans isomers Trans isomers are slightly more stable than cis isomers so have slightly lower heats of hydrogenation (a measure of how much energy they give out)

  10. Rules for naming Alkenes and Alkynes

  11. Alkynes Note: I would call acetylene ethyne

  12. Alkynes

  13. Cycloalkenes

  14. 1-methyl cyclohexene

  15. Plenary: Draw molecular models for
