  • Polar Molecule
    Has uneven charge distribution, resulting in partial positive and negative regions that enable strong interactions with other polar substances.
  • Bent Geometry
    Describes the shape of a molecule where atoms are not arranged in a straight line, leading to unique physical and chemical properties.
  • Bond Angle
    Measures the angle between two adjacent bonds in a molecule, influencing its overall shape and polarity.
  • Dipole Moment
    Represents the separation of charge within a molecule, contributing to its polarity and ability to interact with other molecules.
  • Lone Pair
    Refers to non-bonding electrons on an atom, affecting molecular shape and enabling formation of hydrogen bonds.
  • Hydrogen Bond
    A strong intermolecular attraction involving a hydrogen atom and an electronegative atom, responsible for many unique properties.
  • Boiling Point
    The temperature at which a substance transitions from liquid to gas, influenced by intermolecular forces like hydrogen bonding.
  • Melting Point
    The temperature at which a substance transitions from solid to liquid, reflecting the strength of molecular interactions.
  • Heat Capacity
    Indicates the amount of energy required to raise the temperature of a substance by one unit, linked to molecular structure.
  • Heat of Vaporization
    Amount of energy needed to convert a liquid into a gas at its boiling temperature, highlighting the strength of intermolecular forces.
  • Density
    Describes mass per unit volume, with water exhibiting decreased density upon freezing, allowing ice to float.
  • Surface Tension
    Reflects the cohesive forces at a liquid's surface, enabling water to resist external force and form droplets.
  • Cohesion
    Describes the attraction between molecules of the same substance, resulting in strong internal bonding in water.
  • Adhesion
    Refers to the attraction between water molecules and other polar or charged substances, facilitating interactions with various materials.
  • Dielectric Constant
    Quantifies a solvent's ability to diminish electrostatic interactions, making water highly effective at dissolving polar substances.
  • Hydration Shell
    A layer of water molecules surrounding ions or polar molecules, stabilizing them and enhancing solubility.
  • Electrolyte
    A substance that dissociates into ions in solution, enabling electrical conductivity and forming hydrated complexes in water.
