The forces that hold molecules together in the liquid and solid states are called intermolecular forces and are appreciably weaker. Most substances can exist in either gas, liquid, or solid phase under appropriate conditions of temperature and pressure. Also, the absence of intermolecular forces above the surface of a liquid results in surface tension, the development of a skin on the surface, which causes beading of liquid droplets and also allows light objects to rest on a liquid surface without sinking (e.g., water bugs). In truth, there are forces of attraction between the particles, but in a gas the kinetic energy is so high that these cannot effectively bring the particles together.

Molecules can have any mix of these three kinds of intermolecular forces, but all substances at least have London dispersion forces. We will concentrate on the forces between molecules in molecular substances, which are called intermolecular forces. The bent shape of the molecules leads to gaps in the hydrogen bonding network of ice. 2. Similarly, if a molecule does not have a dipole moment nor monopole moment, then quadrupolar interactions will be important.

There is a large electronegativity difference between the H and the O,N,F Hydrogen bonding Title: Microsoft Word - 5-20a,20b-Molecular Geometry and Forces Wkst-Key.doc Author: Brent White Therefore according to this statement gases will have the higher kinetic energy in comparison to intermolecular forces, solids will gave greater intermolecular forces in comparison to kinetic energy, and liquids are in the middle with kinetic energy less than intermolecular . However, the relevant moments that is important for the IMF of a specific molecule depend uniquely on that molecules properties. The strength of the induced dipole moment, \(\mu_{induced}\), is directly proportional to the strength of the electric field, \(E\) of the permanent moment with a proportionality constant \(\alpha\) called the polarizability. The tendency of a substance to be found in one state or the other under certain conditions is largely a result of the forces of attraction that exist between the particles comprising it.

Table \(\PageIndex{1}\) lists the exponents for the types of interactions we will describe in this lesson. For the most part, only compounds in which hydrogen is covalently bonded to O, N, or F are candidates for hydrogen bonding. An intermolecular force (IMF) (or secondary force) is the force that holds atoms together within. % For example, an uncharged molecule will not have a monopole moment and hence will not have monopole-monopole IMF, nor monopole-dipole or monopole-quadrupole IMFs.
