Advanced Usage
- While "alcohol radical" is a valid term, in modern chemical nomenclature, the group is more precisely and commonly called the hydroxyl group or hydroxy group. The term "radical" in this context is a historical usage meaning a group of atoms that behaves as a unit in chemical reactions, not to be confused with free radicals.
Variants and Related Words
- Hydroxyl group (n): The preferred modern term for the -OH functional group.
- Hydroxy (adj): Used as a prefix in chemical names to indicate the presence of an -OH group, e.g., .
- Alcohol (n): A class of organic compounds containing one or more hydroxyl (-OH) groups attached to a carbon atom.
Synonyms
- Hydroxyl group
- Hydroxy group
Notes on Meaning
- It is critical to distinguish this term from free radicals, which are atoms or molecules with unpaired electrons. The "radical" in "alcohol radical" uses an older definition meaning a characteristic group or moiety within a molecule.
