IGCSE Chemistry Edexcel 4CH1

know that alcohols contain the functional group −OH

**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**

**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**

**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**

understand the reasons for fermentation, in the absence of air, and at an optimum temperature
