Dispersion
all such forces are intermolecular forces.

that would be dipole-dipole forces
The main intermolecular forces between water molecules are hydrogen bonds which are pretty strong as far as intermolecular forces go. Between hydrocarbon chains (oil) the main intermolecular force are London force which are weaker. For two liquids to be miscible the intermolecular forces between them have to be similar in strength or they won't dissolve. Water and oil have different strengths of intermolecular bonds so don't mix.
If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid. Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.
dipole forces and induced dipole forces
methane
dipole-dipole dispersion
These are polar forces, intermolecular forces of attraction between molecules.
Induced dipole forces, or simply, london forces
Ammonia form hydrogen bonds.
London Force / van der Waals force
all such forces are intermolecular forces.
Dipole forces and London forces are present between these molecules.
Esters have carbonyl groups which are polar, so there are dipole-dipole attractions. There will also be van der Waals forces.
Dipole forces and London forces are present between these molecules.
