Intermolecular forces serve to hold particles close together, whereas the particles’ kinetic energy provides the energy required to overcome the attractive forces and thus increase the distance between particles.
In liquids, the attractive intermolecular forces are strong enough to hold molecules relatively close together but not strong enough to keep molecules from moving past each other which of the following exhibits dipole-dipole attraction between molecules
While intramolecular forces determine the chemical properties of a substance, intermolecular forces primarily affect its physical characteristics, including boiling points, melting points, solubility, and viscosity.
Identify the type/s of intermolecular forces that are present between an ammonia (NH 3) molecule and a chloroform (CHCl 3) molecule.
