• Polymers (addition & condensation)
• Carbohydrate macromolecules
• Air & water pollution
• Greenhouse gases
• Acid rain

How Macromolecules and Environmental Chemistry Is Tested

MDCAT questions on Macromolecules and Environmental Chemistry are a mix of recall (definitions, classifications), application (predict outcomes, interpret diagrams), and basic numerical/analytical reasoning. PMDC papers from 2020–2025 emphasized the concepts above; older UHS papers (2008–2019) tested them too, with slight variations in question framing.
