dipole molecule

Thân thiện

A water molecule is a classic example of a dipole molecule.

Definition

1. Noun:
   • A molecule that is a permanent dipole: A dipole molecule is a molecule that possesses a permanent separation of positive and negative electrical charges. This occurs due to an uneven distribution of electrons between atoms with different electronegativities, creating a permanent electric dipole moment.

Usage Examples

• Noun:
  • Water is a classic example of a dipole molecule because of its bent shape and the difference in electronegativity between oxygen and hydrogen.
  • The polarity of a solvent often depends on whether it is a dipole molecule.
  • In an electric field, a dipole molecule will tend to align itself with the field.

Advanced Usage

• "To exhibit dipole molecule characteristics": To display the properties of a permanent dipole.
  • Ammonia (NH₃) exhibits strong dipole molecule characteristics due to its lone pair of electrons and pyramidal shape.

Variants and Related Words

• Dipole moment (n): A quantitative measure of the polarity of a molecule, indicating the magnitude of its dipole.
  • The dipole moment of a molecule determines the strength of its interactions with other dipoles.
• Polar molecule (n): Often used synonymously with dipole molecule, referring to a molecule with a permanent dipole moment.
  • A polar molecule must have a dipole moment that is not zero.

Synonyms

• Polar molecule: A molecule with a permanent dipole moment.
• Electric dipole: A general term for any pair of equal and opposite charges separated by a distance, which can apply to molecules.

Related Phrases

• Molecular dipole: Another term for the dipole inherent to a molecule.
  • The molecular dipole is a vector quantity pointing from the partial positive to the partial negative charge.

Related Concepts

• Dipole-dipole interaction: The attractive force between the positive end of one dipole molecule and the negative end of another.
  • Dipole-dipole interactions are stronger than dispersion forces and contribute to higher boiling points.
