What is the predominant type of intermolecular force in {eq}HF {/eq}? Intermolecular Forces of Attraction: The intermolecular force of a substance is the force responsible for keeping the particles of the substance together. It is highly determined by how the electrons in one particle of th...
The differences in the properties of a solid, liquid, or gas reflect the strengths of the attractive forces between the atoms, molecules, or ions that make up each phase. The phase in which a substance exists depends on the relative extents of itsintermolecular forces(IMFs) and the kinetic ...

Intermolecular forces between n-hexane and n-heptane are nearly same as between hexane and heptane individually. When these two are mixed, which of the following is not true about the solution formed ? View Solution In a DNA molecule distance between two bases is View Solution The potential ...
Three types of intermolecular interactions are considered: van der Waals (vdW), donoracceptor and hydrogen bonds. Are vdW forces caused by instantaneous dipoles created by electrons’ orbiting the nuclei (London)—or by accumulation of electron density between atoms (Feynman, later Bader), broadly ...
in optical absorption energy, called CT transitions22. In contrast to such general and familiar understanding, however, the importance of CT interactions in intermolecular forces has been repeatedly questioned from the viewpoint of ab initio quantum chemical calculations, although the target had to be...
