Nitrogen tribromide intermolecular forces

Custom Search. Intermolecular forces are forces of attraction that hold groups of covalently bonded atoms called molecules to other molecules. Therefore Ionic compounds are technically not held together by IMF's. This is the only force between 2 nonpolar molecules. It is found in all molecules, but usually not acknowledge to it being so weak. An example is Nitrogen. It is nonpolar and can only liquefy by these weak forces.

A little energy and liquid nitrogen will vaporize. Stronger than van der Waals is a Dipole-Dipole Attraction. Yes, it is the interaction of two dipoles aka a polar molecule. Since polar molecules have a slightly positive and slightly negative end they attract very nicely. Much stronger force of attraction than van der Waals, which is present but insignificant in comparison to dipole-dipole forces.

The strongest of the IMF's is hydrogen bonding.

It is NOT what holds 2 hydrogen molecules together that is van der Waals. Hydrogen bonds occur between molecules that have a permanent net dipole resulting from hydrogen being covalently bonded to either fluorine, oxygen or nitrogen.

On to Like Dissolve Like. Chemical Demonstration Videos.Molecules cohere even though their ability to form chemical bonds has been satisfied. The evidence for the existence of these weak intermolecular forces is the fact that gases can be liquefied, that ordinary liquids exist and need a considerable input of energy for vaporization to a gas of independent molecules, and that many molecular compounds occur as solids.

The role of weak intermolecular forces in the properties of gases was first examined theoretically by the Dutch scientist Johannes van der Waalsand the term van der Waals forces is used synonymously with intermolecular forces. Under certain conditions, weakly bonded clusters of molecules such as an argon atom in association with a hydrogen chloride molecule can exist; such delicately bonded species are called van der Waals molecules.

There are many types of intermolecular forces; the repulsive force and four varieties of attractive force are discussed here. In general, the energy of interaction varies with distance, as shown by the graph in Figure Attractive forces dominate to the distance at which the two molecules come into contact, then strong repulsive forces come into play and the potential energy of two molecules rises abruptly.

The shape of the intermolecular potential energy curve shown in the illustration resembles that of the molecular potential energy curve in Figure The minimum of the former is much shallower, however, showing that forces between molecules are typically much weaker than the forces responsible for chemical bonds within molecules.

The repulsive part of the intermolecular potential is essentially a manifestation of the overlap of the wave functions of the two species in conjunction with the Pauli exclusion principle. It reflects the impossibility for electrons with the same spin to occupy the same region of space. Consequently, as the internuclear separation is decreased, the total energy rises steeply. All closed-shell species behave in a similar manner for much the same reason. The first of the four bonding interactions discussed here is the dipole—dipole interaction between polar molecules.

It will be recalled that a polar molecule has an electric dipole moment by virtue of the existence of partial charges on its atoms. Opposite partial charges attract one another, and, if two polar molecules are orientated so that the opposite partial charges on the molecules are closer together than their like charges, then there will be a net attraction between the two molecules.

This type of intermolecular force contributes to the condensation of hydrogen chloride to a liquid at low temperatures. The dipole—dipole interaction also contributes to the weak interaction between molecules in gases, because, although molecules rotate, they tend to linger in relative orientations in which they have low energy—namely, the mutual orientation with opposite partial charges close to one another.

The second type of attractive interaction, the dipole—induced-dipole interaction, also depends on the presence of a polar molecule. The second participating molecule need not be polar; but, if it is polar, then this interaction augments the dipole—dipole interaction described above. In the dipole—induced-dipole interaction, the presence of the partial charges of the polar molecule causes a polarizationor distortion, of the electron distribution of the other molecule.

As a result of this distortion, the second molecule acquires regions of partial positive and negative chargeand thus it becomes polar. The partial charges so formed behave just like those of a permanently polar molecule and interact favourably with their counterparts in the polar molecule that originally induced them. Hence, the two molecules cohere.

This interaction also contributes to the intermolecular forces that are responsible for the condensation of hydrogen chloride gas.

The third type of interaction acts between all types of molecule, polar or not. It is also somewhat stronger than the two attractive interactions discussed thus far and is the principal force responsible for the existence of the condensed phases of certain molecular substances, such as benzeneother hydrocarbonsbromineand the solid elements phosphorus which consists of tetrahedral P 4 molecules and sulfur which consists of crown-shaped S 8 molecules.

The interaction is called the dispersion interaction or, less commonly but more revealingly, the induced-dipole—induced-dipole interaction. Consider two nonpolar molecules near each other. Although there are no permanent partial charges on either molecule, the electron density can be thought of as ceaselessly fluctuating. As a result of these fluctuations, regions of equal and opposite partial charge arise in one of the molecules and give rise to a transient dipole.

This transient dipole can induce a dipole in the neighbouring molecule, which then interacts with the original transient dipole. Although the latter continuously flickers from one direction to another with an average of zero dipole overallthe induced dipole follows it, and the two correlated dipoles interact favourably with one another and cohere.

Every molecule experiences london dispersion as an intermolecular force. Since the ammonia ion has hydrogen atoms bonded to nitrogen, a very electronegative atom, the molecule is also polar since the nitrogen atom more strongly pulls on the electrons from the hydrogen atoms than the hydrogens themselves do. This effect is similar to that of water, where the oxygen pulls the electrons of the hydrogen atoms with a greater magnitude, resulting in the oxygen having a partial negative charge and the hydrogens having a partial positive charge relative to each other.

This polarity shows that the molecule has dipole-dipole intermolecular forces but since the polarity is from a result of highly electronegative atoms such as nitrogen, oxygen, fluorine and hydrogen atoms actually bonded to them, the polarity is categorized in its own intermolecular force called a hydrogen bond.

Water evaporates slower than carbon tetrachloride. Water has strong intermolecular forces hydrogen bonds while carbon tetrachloride only has weaker induced dipole forces. Carbon tetrachloride is non-polar. Substances with stronger intermolecular forces take longer to evaporate than substances with weaker intermolecular forces. Sodium chloride is likely to dissolve in methanol. Sodium chloride is ionic.

Methanol is polar. The type of intermolecular force that can exist when sodium chloride dissolves in methanol is ion-dipole forces. The formation of these forces helps to disrupt the ionic bonds in sodium chloride and so sodium chloride can dissolve in methanol. Tumi and Jason are helping their dad tile the bathroom floor. Their dad tells them to leave small gaps between the tiles.

What is the predominant intermolecular force in each of these compounds?

Why do they need to leave these small gaps? Materials such as tiles expand on heating and so small gaps need to be left between the tiles to allow for this expansion. If Tumi and Jason did not leave these gaps between the tiles, the tiles would soon lift up. Hope returns home from school on a hot day and pours herself a glass of water.
