  1. 5. the principal reaction of alkanes
  2. 6. an organic molecule containing only C-C bonds
  3. 9. the industrial process by which mixtures of similarly sized hydrocarbons are extracted from crude oil
  4. 11. mixtures of similarly sized hydrocarbons derived from crude oil.
  5. 13. the longer the carbon chain in a hydrocarbon, the greater the __________________ between the molecules. More energy is required to break them when boiling the longer hydrocarbon and, consequently, the higher the boiling point. (2 words)
  6. 15. the process by which long alkanes are split into a smaller alkane and an alkene
  7. 17. hydrocarbon containing one or more C=C bonds
  8. 18. the process that separates components of a mixture of liquids with similar boiling points using multiple cycles of vaporisation and condensation (2 words)
  9. 19. the chemistry of carbon containing compounds (2 words)

  2. 2. a sequence of compounds with the same functional group and similar chemical properties in which the members of the series differ by the number of carbons they contain (2 words)
  3. 3. a toxic product of incomplete burning of hydrocarbons (2 words)
  4. 4. a saturated hydrocarbon with 7 carbons in a chain
  5. 7. an organic molecule containing one or more multiple carbon carbon bonds
  6. 8. resources that, once they are used, cannot be replaced on a meaningful timescale. (2 words)
  7. 10. saturated hydrocarbon
  8. 12. a molecule containing only carbon and hydrogen atoms
  9. 14. the process that separates components of a mixture based on their different boiling points
  10. 16. a gas that is generated through the complete burning of hydrocarbons that is a greenhouse gas. (2 words)
