Web9 mrt. 2006 · One peculiar phenomenon is that association can take place even when the protein and the polyelectrolyte carry the same charge. This has been interpreted as if the ion-dipole interaction can overcome the repulsive ion-ion interaction. WebWhen NaCl dissolves in water, aqueous Na+ and Cl- ions result. The force of attraction that exists between Na+ and H2O is called a(n) _____ interaction. A) dipole-dipole B) ion-ion C) hydrogen bonding D) ion-dipole E) London dispersion force
Web29 dec. 2024 · Ion-dipole attractions only occur in a mixture of an ionic compound and polar molecules. These attractions occur when ions (cations or anions) are attracted to the positive or negative end of a dipole. Overall, this IMF is stronger than dipole-dipole and H-Bonding.
