C
Which of the following correctly identifies the intermolecular force represented by B and compares its strength relative to the
intermolecular force represented by C? (5 points)
No
D

A. B represents ion-dipole forces, which are weaker than the force represented by C.

B. B represents dipole-dipole forces, which are weaker than the force represented by C.

C. B represents ion-dipole forces, which are stronger than the force represented by C.

D. B represents dipole-dipole forces, which are stronger than the force represented by C.

Answer 1

B represents dipole-dipole forces, which are weaker than the force represented by C. Option B

Are dipole forces weaker than the hydrogen bond?

The attraction between the positive ends of two polar molecules and their respective negative ends is what causes dipole-dipole forces. These forces cause partial positive and negative charges in molecules with permanent dipoles because of the unequal distribution of electrons in these molecules.

Because of the significant difference in electronegativity between hydrogen and the electronegative element, the hydrogen bond is stronger than a conventional dipole-dipole interaction.
