Hydrogen bonding.
Hydrogen bonding is a dipole-dipole interaction in which a hydrogen atom bonded to a highly electronegative atom (either O, N, or F) develops a partial positive charge. This partial positive charge allows the formation of a weak bond with another electronegative atom (again, either O, N, or F).

between molecules the forces are called intermolecular forces, and between the atoms in a molecule they are called inramolecular forces

No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.
"van der waals" forces.
Within the molecule, covalent bonds hold them together. Between the molecules there can be several different forces. There are dipole-dipole attractions, hydrogen bonds and van der Waals forces. Which of them apply in a particular substance depends on the structure of the molecules.

all such forces are intermolecular forces.
The strong forces of attraction between the positive and negative regions of molecules are called electrostatic forces or electrostatic interactions.
There are no bonds between hexane molecules. There are intermolecular forces, called London Dispersion Forces which attract other hexane molecules.

When molecules are close together, a slight attraction can develop between the oppositely charged regions of nearby molecules. Chemists call such intermolecular forces of attraction van der Waals forces. (This also occurs in the phenomenon known as Hydrogen-bonding.) What is the alternate of a slight attraction - it is called the covalent bond. Note that an ionic bond is a type of covalent bond.
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.

Molecules are composed of two or more atoms linked together. The attractive forces that link these atoms together are called chemical bonds. The same idea is with forces , except on a larger scale. Forces link MOLECULES to MOLECULES. Bonds link ATOMS to ATOMS.
The predominant force between IBr molecules in liquid IBr is Van der Waals forces, specifically dipole-dipole interactions and London dispersion forces. These forces are responsible for holding the IBr molecules together in the liquid state.
