Secondary revision · Chemistry Form 4
Macromolecules (Polymers)
This topic expands on organic chemistry to cover giant molecules known as polymers, both natural (like starch and proteins) and synthetic (like polyethene and nylon). As per the Zambian CBC, you will learn about addition and condensation polymerization, the structure and properties of plastics, and their widespread uses. A crucial part of this topic is investigating the environmental impact of non-biodegradable polymers and exploring solutions. ECZ exams may ask you to draw repeating units, identify monomers, or discuss environmental issues related to plastics. Understanding macromolecules connects chemical principles to real-world materials science and environmental sustainability, key areas for modern chemistry assessment.
