| (e) Alcohols (This topic is not required for Double Award Science) |
| 4.29C know that alcohols contain the functional group -OH |
| 4.30C understand how to draw structural and displayed formulae for methanol, ethanol, propanol (propan-1-ol only) and butanol (butan-1-ol only), and name each compound (the names propanol and butanol are acceptable) |
4.31C know that ethanol can be oxidised by:
- burning in air or oxygen (complete combustion)
- reaction with oxygen in the air to form ethanoic acid (microbial oxidation)
- heating with potassium dichromate(VI) in dilute sulfuric acid to form ethanoic acid
|
4.32C know that ethanol can be manufactured by:
- reacting ethene with steam in the presence of a phosphoric acid catalyst
at a temperature of about 300oC and a pressure of about 60–70 atm
- the fermentation of glucose, in the absence of air, at an optimum temperature of about 30oC and using the enzymes in yeast
|
| 4.33C understand the reasons for fermentation, in the absence of air, and at an optimum temperature |
