Stronger Forcing

Distinguish between dipole-dipole attraction forces and dispersion (London) forces. Is one type of these intermolecular forces stronger than the other Explain. [Pg.215]

More generally, it is widely recognized that it is the establishment of repulsive electrostatic forces stronger than attractive van der Waals forces that is the main effective mechanism preventing aggregation of biopolymer molecules and colloidal particles in stable aqueous systems. [Pg.126]

Chemisorption of inhibitor molecules on metals is slow and involves interaction forces stronger than the forces in physisorption. A coordinate type of bond between the metal and the inhibitor is thought to be present with charge transfer from the inhibitor to the metal.55 An opposing view is that a chemical bond is not necessarily present in chemisorption of an inhibitor on the metal surface.56 In some cases the temperature dependence shows higher inhibition efficiency and higher activation energy than physisorption. [Pg.84]

Why are dipole-dipole forces stronger than dispersion forces for molecules of comparable mass ... [Pg.395]

Why is there no change in wtramolecular forces when a solid is melted Are intramolecular forces stronger or weaker than intermolecular forces ... [Pg.471]

What are London dispersion forces and how do they arise in a nonpolar molecule Are London forces typically stronger or weaker than dipole-dipole attractions between polar molecules Are London forces stronger or weaker than covalent bonds Explain. [Pg.472]

In which substance, benzene or toluene, are the intermolecular forces stronger In which substance do the molecules pack more efficiently ... [Pg.486]

Dipole forces, stronger than dispersion forces, are present in polar molecules. Polar molecules have permanent dipoles that result in strong attractions between... [Pg.327]

Electrostatic interactions between dispersed molecules are significantly affected by the dielectric constant of the medium. A decrease in the dielectric constant caused, for example, by the addition of some organic solvents (alcohols or ketones), makes the mutual electrostatic attractive forces stronger and the dispersed particles can form clusters or coagulate. This phenomenon is employed for the isolation of some polysaccharides (such as agar, carrageenan... [Pg.494]
