Thân thiện

An intramolecular reaction rearranges the bonds within a single molecule.

Definition

1. Adjective:
   • Within a single molecule: Describing something that exists, occurs, or acts inside the confines of an individual molecule.
   • Involving parts of the same molecule: Pertaining to forces, interactions, or reactions that take place between different atoms or groups within the same molecule, rather than between separate molecules.

Usage

The adjective intramolecular is used primarily in scientific contexts, especially chemistry, physics, and biochemistry, to describe phenomena internal to a molecule. It is the opposite of intermolecular, which describes interactions between different molecules.

Examples

• Adjective:
  • The stability of the protein's folded shape is due to strong intramolecular hydrogen bonds.
  • An intramolecular reaction can form a ring structure from a linear chain of atoms.
  • Scientists studied the intramolecular forces that hold the complex organic compound together.

Advanced Usage

• "intramolecular force": A force that acts between atoms within a single molecule, such as covalent bonds or internal hydrogen bonds.
  • Covalent bonds are a powerful type of intramolecular force.
• "intramolecular catalysis": A catalytic reaction where the catalyst is part of the same molecule as the substrate.
  • The reaction proceeds rapidly due to intramolecular catalysis.

Variants and Related Words

• Intramolecularly (adverb): In an intramolecular manner.
  • The energy is transferred intramolecularly.
• Intermolecular (adjective): Existing or occurring between different molecules. (This is the key antonym of ).

Synonyms

• Internal (to the molecule): A more general synonym in a scientific context.
• Intra-atomic is not a synonym; it refers to within an atom, not a molecule.

Antonyms

• Intermolecular: Between molecules.
