CHEM191
ASSIGNMENT 8
Due: Monday 3rd February
The assignment is in two parts and worth a total of 30 marks.
Part A - A useful organic compound (10 marks)
Choose one of the compounds below (or you can choose your own organic molecule but check with Tylah first) and write about its discovery or synthesis and its usefulness to society (focus on one application). You should attempt to find a link between the molecule and its usefulness. You should consult and reference at least 3 different sources and collate the information into a coherent,
concise paragraph which includes:
• The molecular formula
• The structural formula
• The functional group/groups in the molecule
• A short summary (300 words) of the usefulness (linking the application to the structure) and the discovery or synthesis of the compound.
|
Vitamin C, caffeine, nylon, aspirin, glucose, penicillin, acetic acid, sodium stearate, rubber, DDT, morphine, progestin, polythene, quinine
|
Please note: you are required to write a “summary” so this means that you should collect ideas from various references and combine the ideas in your own words. Your work will be checked for plagiarism so be sure to present your ideas in your own words.
The marking rubric for the writing is shown below.
