Question

What is the strongest intermolecular force between acetone

dipole dipole, hydrogen, or london

Answer 1

The strongest intermolecular forces between the acetone molecules are the dipole-dipole forces, as acetone has a strong dipole due to the presence of the carbonyl group. So, it can involve in dipole-dipole forces with another acetone molecule as shown below-

This is because, the hydrogen bonding is not present between the acetone molecules, so the only intermolecular forces are

• Dipole-dipole and
• London dispersion forces,

Now, the London forces are the weakest intermolecular forces among all. So, obviously the strongest is the dipole-dipole.
