🔍 Key Concepts

• Chlorofluorocarbons (CFCs) and what the letters in the name actually stand for • Difference between hydrogenated and halogenated compounds in basic chemistry • How replacing hydrogen atoms with halogen atoms (like chlorine and fluorine) changes a molecule

💭 Think About

• Look at the full name of CFCs and match each part (chloro, fluoro, carbon) to what type of atoms are present or absent • Ask yourself: if a compound is "hydrogenated," what element must be present in significant amount? Do CFCs emphasize hydrogen or other elements? • Consider what happens when hydrogen atoms in a hydrocarbon are replaced by halogens such as chlorine and fluorine—does that make the compound partially or completely halogenated?

✅ Before You Answer

• Verify what the letters C, F, and C stand for in the term CFC • Check whether CFCs are known for containing hydrogen or for containing chlorine and fluorine instead • Confirm whether the definition of fully vs. partially halogenated refers to how many hydrogen atoms have been replaced by halogen atoms
