dipolar

A scientist draws the dipolar field lines around a bar magnet.

Definition
  1. Adjective:
    • Having two poles: In physics and chemistry, "dipolar" describes a system, molecule, or field that possesses two distinct and opposite poles, such as positive and negative electric charges or north and south magnetic poles.
    • Characterized by a dipole moment: It specifically refers to having a separation of equal but opposite charges or magnetic poles by a small distance, creating a measurable dipole moment.
Usage Examples
  • Adjective:
    • Water is a dipolar molecule because of the uneven distribution of electrons between the oxygen and hydrogen atoms.
    • The bar magnet is a classic example of a dipolar magnetic field.
    • Scientists studied the dipolar nature of the compound to understand its solubility.
Advanced Usage

  • "dipolar interaction": A force or interaction between two dipoles, such as the attraction between the positive end of one polar molecule and the negative end of another.

    • The properties of many liquids are influenced by dipolar interactions between their molecules.

  • "dipolar aprotic solvent": A type of solvent that has a significant dipole moment but no hydrogen atom bonded to an electronegative atom (like oxygen or nitrogen), and thus cannot donate hydrogen bonds.

    • Dimethyl sulfoxide (DMSO) is a common dipolar aprotic solvent used in organic reactions.
Variants and Related Words

  • Dipole (n): A pair of equal and opposite electric charges or magnetic poles separated by a distance.

    • An electric dipole consists of a positive and a negative charge.

  • Dipole moment (n): A measure of the separation of positive and negative electrical charges in a system.

    • The dipole moment of a molecule indicates its overall polarity.
Synonyms
  • Bipolar: Having two poles or extremities. (Note: In technical contexts, "bipolar" is often used similarly, but "dipolar" is more specific to physics and chemistry regarding charge/pole separation.)
  • Polar: Having a dipole moment; exhibiting polarity.
Related Phrases and Compounds
  • Dipolar compound: A chemical compound that possesses a permanent dipole moment.
  • Dipolar cycloaddition: A specific type of chemical reaction involving molecules with dipolar characteristics.
