1. “Do Now” Quiz

2. What does the term hydrocarbon mean?1.

3. What is the feature of an alkane?2.

4. How many bonds can a carbon have?3.

5. What is the general formula of an alkane?4.

6. How many Hydrogens would an alkane with 256 Carbons have?5.

7. What is the prefix (beginning of the word) for a hydrocarbon with 4 carbons?6.

8. Name the following hydrocarbon:7.

9. What is the “functional group” of an alkene?8.

10. Draw Propene.9.

11. True or False.Shorter carbon chain hydrocarbons have lower boiling points making them more volatile.10.

12. What are the two main fractions we use the most from crude oil?11.

13. What is the process called that we use to separate crude oil into its fractions?12.

14. True or false.In the fractional distillation column it is cooler at the bottom and hotter at the top.13.

15. Pick the correct words.Short chain hydrocarbons have high/low boiling points so come off at the top/bottom of the column because it is cooler/hotter.14.

16. When the crude oil is heated it boils and does what?15.

17. What does the term hydrocarbon mean?1.A compound containing hydrogen and carbon

18. What is the feature of an alkane?2.Carbon to Carbon Single Bonds

19. How many bonds can a carbon have?3.Four

20. What is the general formula of an alkane?4.CnH2n+2

21. How many Hydrogens would an alkane with 256 Carbons have?5.514

22. What is the prefix (beginning of the word) for a hydrocarbon with 4 carbons?6.But-

23. Name the following hydrocarbon:7.Pentane

24. What is the “functional group” of an alkene?8.C=C

25. Draw Propene.9.

26. True or False.Shorter carbon chain hydrocarbons have lower boiling points making them more volatile.10.True

27. What are the two main fractions we use the most from crude oil?11.Petrol and Diesel

28. What is the process called that we use to separate crude oil into its fractions?12.Fractional Distillation

29. True or false.In the fractional distillation column it is cooler at the bottom and hotter at the top.13.False

30. Pick the correct words.Short chain hydrocarbons have high/low boiling points so come of at the top/bottom of the column because it is cooler/hotter.14.Low, top, cooler

31. When the crude oil is heated it boils and does what?15.Evaporate (or turns into a gas)

33. Why would there be a high demand for fuels that contain short chain hydrocarbons?

34. There is a high demand in short chain molecules because these are more useful than long chain hydrocarbonsWe change the long chain hydrocarbons into smaller, more useful ones that can be used as fuels for carsLONG CHAIN MOLECULE SHORT CHAIN MOLECULE + ALKENETesting for an alkene:Add ORANGE bromine water, if an alkene is present it will go from orange to colourlessCRACKINGNOT USEFUL USEFUL

35. Steam crackingLong chain hydrocarbons are heated to turn them into a gasThe hydrocarbon gas is mixed with steamThen heated to a very high temperature which splits them into smaller moleculesCatalytic crackingLong chain hydrocarbons are heated to turn them into a gasThe hydrocarbon gas is passed over hot powdered aluminium oxide catalystThe long chain molecules split apart on the surface of the specks of catalyst

36. You may be asked to workout the formula:C10H22  C8H18 + ________Decane  Octane + _______

37. AssessmentIn small groups fill in as much of your sheet as you can WITHOUT your notes.As soon as you have done as much as you can without you can THEN start to use your notes to help you.
