#9.26C
Recall the formulae of molecules of the alcohols, methanol, ethanol, propanol (propan-1-ol only) and butanol (butan-1-ol only), and draw the structures of these molecules, showing all covalent bonds
#9.27C
Recall that the functional group in alcohols is –OH and that alcohols can be dehydrated to form alkenes
#9.28C
Core Practical: Investigate the temperature rise produced in a known mass of water by the combustion of the alcohols ethanol, propanol, butanol and pentanol
#9.29C
Recall the formulae of molecules of the carboxylic acids, methanoic, ethanoic, propanoic and butanoic acids, and draw the structures of these molecules, showing all covalent bonds
#9.30C
Recall that the functional group in carboxylic acids is –COOHand that solutions of carboxylic acids have typical acidic properties
#9.31C
Recall that ethanol can be oxidised to produce ethanoic acid and extend this to other alcohols (reagents not required)
#9.32C
Recall members of a given homologous series have similar reactions because their molecules contain the same functional group and use this to predict the products of other members of these series
#9.33C
Describe the production of ethanol by fermentation of carbohydrates in aqueous solution, using yeast to provide enzymes
#9.34C
Explain how to obtain a concentrated solution of ethanol by fractional distillation of the fermentation mixture
