Verified step by step guidance
1
Understand what a chlorofluorocarbon (CFC) is: CFCs are compounds composed of carbon (C), chlorine (Cl), and fluorine (F) atoms, often used as refrigerants or propellants.
Examine each compound to identify the elements present:
- CH4 contains carbon and hydrogen only.
- CCl2F2 contains carbon, chlorine, and fluorine, matching the definition of a CFC.
- NH3 contains nitrogen and hydrogen only, and CO2 contains carbon and oxygen only, so neither are CFCs.
