Question

The strongest intermolecular interactions between hydrogen fluoride (HF) molecules arise from A) dipole dipole forces B) hydrogen bonding C) ion dipole interactions D) ionic bondsE) London dispersion forces

Answer 1

The answers are: A) dipole-dipole forces and B) hydrogen bonding

Step-by-step explanation:

Hydrogen bonds are a class of bond that form from the attraction between a hydrogen atom and an atom that has a negative charge. This attraction is known by the name of dipole-dipole interaction.

In this case, since the hydrogen atom has a low electronegativity and since the fluorine atom has a high electronegativity, therefore, between them there will be a positive charge on the hydrogen atom and a negative charge on the fluorine atom. . In this way, they will have hydrogen bonds between the hydrogen atom and the fluorine atom.

The attached figure shows the bonds.

Answer 2

B)

Step-by-step explanation:

Hydrogen boding

Is a primarily electrostatic force of attraction between a hydrogen atom which is covalently bound to a more electronegative atom or group, particularly the second-row elements.
