Esters exhibit several types of intermolecular forces, primarily dipole-dipole interactions due to the polar carbonyl (C=O) group and the ether-like (C-O) bond. They also experience London dispersion forces, which are present in all molecules, regardless of polarity. However, hydrogen bonding is generally weak in esters compared to carboxylic acids, as esters lack the hydrogen atom directly bonded to an electronegative atom (like oxygen or nitrogen) that would facilitate stronger hydrogen bonding.
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.
Dipole-dipole attraction and van der Waals forces.
Dispersion forces (London dispersion forces) are generally the weakest type of intermolecular force. These forces are caused by temporary fluctuations in electron distribution around atoms or molecules, leading to weak attractions between them.
The intermolecular force in CCl4 is dispersion forces. This occurs when slight variations in electron distribution effect the electron distribution of other molecules. Because CCl4 is non polar, it does not have other intermolecular forces holding the molecules together.
C10H22, known as decane, primarily exhibits London dispersion forces (also called van der Waals forces) as its main type of intermolecular force. These forces arise due to temporary dipoles that occur when the electron distribution around the molecule fluctuates. Since decane is a nonpolar hydrocarbon, it lacks significant dipole-dipole interactions or hydrogen bonding. Thus, the strength of its intermolecular forces is relatively weak compared to polar substances.

There are no bonds between hexane molecules. There are intermolecular forces, called London Dispersion Forces which attract other hexane molecules.
Van der Waals forces, specifically London dispersion forces, exist between octane molecules. These forces are weak compared to other intermolecular forces like hydrogen bonding, but they are sufficient to hold octane molecules together in a liquid state.
Dipole forces and London forces are present between these molecules.

Intermolecular forces, such as hydrogen bonding, van der Waals forces (including dipole-dipole interactions and London dispersion forces), and ion-dipole interactions, act between molecules. These forces help hold molecules together in a substance.
