  • There are three types of intermolecular forces: dispersion (London) forces, dipole-dipole interactions, and hydrogen bonding.
  • Intermolecular forces are responsible for the properties of matter, such as boiling point, melting point, viscosity, surface tension, and density.
  • The intermolecular force is the attractive or repulsive interaction between molecules.
  • Dispersion forces arise from the temporary fluctuations in electron density around all atoms and molecules due to their motion.
  • The strength of an intermolecular force depends on several factors, including the size of the molecule, its shape, the presence or absence of polar bonds, and the number of electrons involved in covalent bonds.
  • Dispersion forces arise from fluctuations in electron distribution within atoms and molecules.
  • Dipole-dipole interactions occur between polar molecules with permanent dipoles that attract or repel one another depending on the orientation of the dipoles.
  • Dipole-dipole interactions occur when two polar molecules interact with one another through electrostatic attraction.
  • Dipole-dipole interactions occur when two polar molecules interact with one another.
  • Molecules with more electrons have stronger intermolecular forces than those with fewer electrons.
  • Dipole-dipole interactions occur between two polar molecules with opposite partial charges.
  • Hydrogen bonds form when an electronegative atom shares its lone pair of electrons with a nearby hydrogen atom, resulting in a strong attraction between them.
  • Hydrogen bonds form between a hydrogen atom covalently bound to an electronegative element and an adjacent electronegative atom.
  • Hydrogen bonding occurs when hydrogen is attached to highly electronegative elements like nitrogen, oxygen, or fluorine, resulting in strong attractions between these molecules.
  • Hydrogen bonding occurs when a hydrogen atom that is bound to an electronegative element forms a strong attraction to an adjacent electronegative atom.
  • Polar molecules have permanent dipoles that can interact through dipole-dipole forces.
  • Hydrogen bonding occurs when hydrogen is bound to highly electronegative elements such as fluorine, oxygen, or nitrogen.
  • Hydrogen bonding is a special type of dipole-dipole interaction that occurs only between certain types of molecules.
  • Intermolecular forces are responsible for the physical properties of matter such as boiling point, melting point, viscosity, surface tension, density, and cohesion/adhesion.
  • Ionic compounds consist of positively charged metal ions (cations) and negatively charged nonmetal ions (anions), held together by electrostatic attraction.
