Intermolecular forces are mainly responsible for the physical characteristics of the substance. Intermolecular forces are responsible for the condensed states of matter. The particles making up solids and liquids are held together by intermolecular forces and these forces affect a number of the physical properties of matter in these two states.

Feb 13, 2019 · The strengths of London dispersion forces also depend significantly on molecular shape because shape determines how much of one molecule can interact with its neighboring molecules at any given time. For example, part (b) in Figure \(\PageIndex{4}\) shows 2,2-dimethylpropane (neopentane) and n-pentane, both of which have the empirical formula C ...
As the surface area of a molecule increases, so does the occurrence of dispersion forces. As a result, longer-chain alkanes (listed in Table 3.5.1) possess higher boiling points. Those are the three kinds of intermolecular forces: hydrogen bonding, dipole-dipole interactions and London dispersion forces. You can see them listed in Table 3.5.2 ...
Jan 25, 2023 · The nature of the chemical species involved in intermolecular forces matters, so there is no hard-and-fast ranking of strongest to weakest intermolecular forces. But, ion-dipole interactions tend to be the strongest, followed by hydrogen bonding, other types of dipole-dipole bonding, and London dispersion forces.
Jan 23, 2023 · The formula of each entry is followed by its formula weight in parentheses and the boiling point in degrees Celsius. First there is molecular size. Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules ...
The transient dipole induces a dipole in the neighboring. A transient dipole-induced dipole interaction, called London dispersion force or wander Wall’s force, is established between the neighboring molecules as illustrated in Fig. 3.9.9. Although London dispersion forces are transient, they keep re-appearing randomly distributed in space and ...
Intramolecular forces are those within the molecule that keep the molecule together, for example, the bonds between the atoms. Intermolecular forces are the attractions between molecules, which determine many of the physical properties of a substance. Figure 11.1.4 illustrates these different molecular forces. The strengths of these attractive ...
