2. What is the difference between a ketone and an aldehyde?
- A ketone can be formed from the oxidation by distillation of a primary alchol
- A ketone has an C=O group in the middle of it's molcule, thus with an alkyl group on each side. In an aldehyde the C=O is found at the end of the molecule with an H and an alkyl group
- An aldehyde has an C=O group in the middle of it's molcule, thus with an alkyl group on each side. In a ketone the C=O is found at the end of the molecule with an H and an alkyl group
- An ketone will form a dark red precipitate of Copper(I) Oxide with Fehling's solution but an aldehyde will not

- (a) No, it has a halogen and no hydrogen (b) No, it doesn't contain H and Cs only (c) Yes, carbon can only make 4 bonds
- (a) Yes. It contains mainly carbon (b) No, it contains flourine (c) No, It has a double bond
- (a) No, It contains flourine (b) No, there is no hydrogen (c) Yes, it has the full number atoms bonded to each C
4. What are some of the issues with bioethanol and biodisel?
- It is non renewable
- It is not as close to carbon neutral as some fossil fuels such as coal
- It uses large areas of land and has substantial costs in processing and manufacture
- Engines will have to be drastically remodeled to run it
