Week 21: Students learned about
>> uses of plastics and of man-made fibres [nylon and Terylene] and the pollution problems caused by non-biodegradable plastics
>> Differences between condensation and addition polymerisation
>> Formation of nylon (a polyamide) and Terylene (a polyester) by condensation polymerisation.
Week 20: Students learnt about
> Alcohol - Manufacturing of ethanol by fermentation and by the catalytic addition of steam to ethene, properties of ethanol in terms of burning, name the uses of ethanol as a solvent and as a fuel and outline the advantages and disadvantages of these two methods of manufacturing ethanol
> Carboxylic acid - The properties of aqueous ethanoic acid,The formation of ethanoic acid by the oxidation of ethanol by fermentation and with acidified potassium manganate(VII), ethanoic acid as a typical weak acid, the reaction of a carboxylic acid with an alcohol in the presence of a catalyst to give an ester
