Making Connections (11 marks)
1. We did two labs involving esters. In the first, we made a series of esters. In the second, we
made two polyesters. Describe at least 3 ‘real world’ uses that you could imagine for the
products of either of these labs based on your observations and data table. (3 marks)
2. In designing a product, such as a diaper, why is knowledge of organic chemistry essential? In
your answer, try to use 2 specific examples or concepts from the course. (4 marks)
3. Explain why your knowledge of organic chemistry can help you to understand the dangers of the
real world. Choose either CFCs or trans fats (or both) to use as a specific example. (4 marks)
