🔍 Key Concepts

• Ozone depletion potential (ODP) of different refrigerant families • Differences between chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs) • How the presence of chlorine in a refrigerant’s chemical structure affects the ozone layer

💭 Think About

• Identify which choices are CFCs, which are HCFCs, and which are HFCs • Ask yourself: which refrigerant group was developed to be chlorine‑free as a replacement for older ozone‑depleting refrigerants? • Eliminate any option you know contains chlorine in its chemical formula or is historically linked with ozone depletion concerns

✅ Before You Answer

• Verify which options are known CFCs (high ozone depletion potential) • Verify which option is an HFC with no chlorine in its molecule • Confirm which refrigerant type is widely cited in environmental regulations as having zero ozone depletion potential (ODP)
