Final answer:
Radicals in chemistry can be classified into three categories: alkyl radicals, aryl radicals, and acyl radicals. Each category has different characteristics and is formed from different types of molecules.
Step-by-step explanation:
The question asks to classify the radicals into the appropriate categories. In chemistry, radicals are classified into three categories: alkyl radicals, aryl radicals, and acyl radicals.
1. Alkyl radicals: These are formed when a hydrogen atom is removed from an alkane molecule. They contain only carbon and hydrogen atoms.
Example: CH₃• (methyl radical)
2. Aryl radicals: These are formed when a hydrogen atom is removed from an aromatic hydrocarbon (ring-shaped molecule). They also contain only carbon and hydrogen atoms.
Example: C₆H₅• (phenyl radical)
3. Acyl radicals: These are formed when a hydrogen atom is removed from a carboxylic acid molecule. They contain both carbon, hydrogen, and oxygen atoms.
Example: CH₃CO• (acetyl radical)
