hydrogen bond
The HF MO diagram is important for understanding how the bonding occurs in the HF molecule. It shows how the atomic orbitals of hydrogen and fluorine combine to form molecular orbitals, which determine the bonding and structure of the molecule. This diagram helps explain the strength and nature of the bond between hydrogen and fluorine in HF.
The primary attractive forces that need to be overcome to dissolve CsI in HF are ionic bonding between Cs+ and I- ions in CsI and hydrogen bonding between HF molecules. Ionic bonding involves the strong electrostatic attraction between oppositely charged ions, while hydrogen bonding involves the attraction between the partially positive hydrogen atom in HF and the partially negative fluorine atom in another HF molecule. Applying energy through stirring or heating helps disrupt these attractive forces and allow CsI to dissolve in HF.
In the molecular orbital configuration of HF, the fluorine 2p orbital forms a sigma bond with the hydrogen 1s orbital, resulting in the formation of a sigma bonding orbital and a sigma antibonding orbital. The electrons occupy the sigma bonding molecular orbital.
Hydrogen fluoride (HF) is less viscous than water (H2O) because HF molecules have lower intermolecular forces and weaker hydrogen bonding compared to water molecules. This results in easier flow of HF molecules past each other, reducing viscosity. Additionally, HF has a lower molecular weight and smaller size, which also contribute to its lower viscosity compared to water.
In HF, there is one nonbonding electron on the fluorine atom. Hydrogen only has one electron, which is used for bonding with fluorine.
HF molecules form hydrogen bonds.
Hydrogen fluoride, with the chemical formula HF, is a colorless gas that is the principal source of fluorine. The type of intermolecular forces that exist in HF are London forces, dipole-dipole.

The dominant intermolecular force in HF is hydrogen bonding. This is a strong dipole-dipole attraction that occurs between the slightly positive hydrogen atom of one HF molecule and the slightly negative fluorine atom of another HF molecule.

The text book answer is that Cl is not electronegative enough (compared to HF where there is obvious H bonding present)
The principal reason is the hydrogen bonding between HF molecules. The second reason is that London dispersion forces will be higher in HF because it has more electrons than H2

in hf there is present strong hydrogen bonding and hydrogen being partially positive is entrapped with two stong partailly electronegative ions.
