Acetone, also known as propanone, is a molecule that has a simple molecular structure. It is made up of carbon, hydrogen, and oxygen atoms. The intermolecular forces possible between molecules of acetone are:

1. Dipole-Dipole Interaction: Acetone is a polar molecule. This means that it has a positive and a negative end, or a dipole. The positive end of one acetone molecule will be attracted to the negative end of another acetone molecule. This is known as a dipole-dipole interaction.

2. London Dispersion Forces: These are also known as Van der Waals forces. They are the weakest type of intermolecular force and occur between all molecules, polar and nonpolar. They arise from the temporary fluctuations in electron distribution within molecules, which generate temporary dipoles. These temporary dipoles induce dipoles in neighboring molecules, leading to attractions.

3. Hydrogen Bonding: This is a special type of dipole-dipole interaction that occurs when a hydrogen atom is bonded to a highly electronegative atom (like nitrogen, oxygen, or fluorine) and is in close proximity to another electronegative atom. However, in the case of acetone, there is no hydrogen atom bonded directly to an oxygen atom, so there is no hydrogen bonding between acetone molecules.

So, the intermolecular forces possible between molecules of acetone are dipole-dipole interactions and London dispersion forces.
