Definition
- Noun:
- A specific chemical group: The
azido groupis the univalent (having a valence of one) chemical group with the formula N₃⁻. It is derived from, or related to, hydrazoic acid (HN₃).
Usage
The term azido group is used exclusively in scientific contexts, particularly in chemistry, biochemistry, and materials science. It refers to the specific anion or functional group composed of three nitrogen atoms. * It functions as a subject or object in a sentence describing chemical structure, reactions, or properties. * Example: The presence of an azido group makes this compound highly energetic. * Example: Researchers introduced an azido group into the organic molecule.
Examples
- Noun:
- The
azido groupis known for its participation in the "click chemistry" reaction called the azide-alkyne cycloaddition. - Safety protocols are strict when handling compounds containing the reactive
azido group.
Advanced Usage
- As a functional group: In organic chemistry, the (-N₃) is treated as a substituent that can be added to a larger molecule, often to enable further specific chemical reactions.
- Example: The polymer was functionalized with an
azido groupat its terminus.
Variants and Related Words
- Azide (n): This is the more general term for any chemical compound containing the N₃⁻ group. An is the functional group itself, while "azide" often refers to the whole salt or compound (e.g., sodium azide, organic azide).
- Azido- (prefix): Used as a prefix in systematic chemical names to indicate the presence of the azido group, e.g., azidomethyl, azidobenzene.
Synonyms
- N₃ group: A purely formulaic synonym.
- Triazanyl group: A systematic name, less commonly used than .
