Use the drop-down menus to match the type of intermolecular force to its name.
Dipole-dipole interactions
Dipole-induced dipole interactions
London dispersion forces
Hydrogen bond
van der Waals forces

Dipole-dipole interactions : occur between polar molecules

Dipole-induced dipole interactions: occur between polar and nonpolar molecules

London dispersion forces: occur in all substances, but are the most important in nonpolar substances

Hydrogen bond: electrostactic attraction between a hydrogen atom and a highly electronegative atom

van der Waals forces: electrostatic interactions between partially charged regions of a molecule

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
