Vector

Definition

A vector is a quantity that has both magnitude and direction. In chemistry, vectors are used to represent properties such as bond dipoles in molecules.

5 Must Know Facts For Your Next Test

1. Vectors can represent bond dipole moments, which indicate the polarity of a chemical bond.
2. The direction of a vector in a molecule points from the less electronegative atom to the more electronegative atom.
3. The net dipole moment of a molecule is found by vector addition of individual bond dipoles.
4. Molecular geometry affects how vectors (dipole moments) combine to determine overall molecular polarity.
5. Vectors are essential for understanding molecular interactions and predicting physical properties like boiling and melting points.

Bond Dipole Moment: A measure of the polarity of a chemical bond, represented as a vector pointing from the less electronegative atom to the more electronegative atom.

Electronegativity:

A property that describes an atom's ability to attract and hold electrons within a chemical bond.

Molecular Geometry:

The three-dimensional arrangement of atoms in a molecule, which influences how vectors (dipole moments) combine.
