benzene formula
Học thuậtThân thiện
Definition
Noun: - A structural representation of benzene: The benzene formula specifically refers to the symbolic depiction of the benzene molecule, which consists of a closed ring (chain) of six carbon atoms, each bonded to one hydrogen atom.
Usage
- The term is used in chemistry to denote the classic hexagonal diagram representing the benzene molecule, C₆H₆.
- It emphasizes the cyclic structure, distinguishing it from a simple molecular formula.
Examples
- The benzene formula, with its alternating double bonds, is a fundamental concept in organic chemistry.
- When drawing the benzene formula, chemists often use a circle inside the hexagon to represent resonance.
Advanced Usage
- As a conceptual model: The benzene formula is not just a drawing but a model representing the molecule's resonance and stability.
- Understanding the benzene formula is key to grasping aromaticity.
Variants and Related Words
- Benzene ring (n): The cyclic arrangement of six carbon atoms that forms the core structure of benzene and many other compounds.
- Many pharmaceuticals contain a benzene ring in their structure.
- Kekulé structure (n): A historical name for a specific representation of the benzene formula with alternating single and double bonds.
- Molecular formula of benzene: C₆H₆. This is a distinct term stating the number of atoms, not the structural arrangement.
Synonyms
- Benzene structure: A more general term for the arrangement of atoms in benzene.
- Benzene diagram: Emphasizes the formula as a drawn representation.
Notes
- The reference definition describes it as "a closed chain of 6 carbon atoms with hydrogen atoms attached." This accurately captures the core idea of the structural formula, focusing on the cyclic carbon skeleton with attached hydrogens. It is a specialized term primarily used in scientific and educational contexts.
Noun
- a closed chain of 6 carbon atoms with hydrogen atoms attached
