#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 60–70atm
- 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
