Intermolecular Forces in Acetone

The video explores the intermolecular forces in acetone, a molecular compound. It begins by confirming the absence of ions and then examines the polarity of acetone using its Lewis structure and 3D model. The analysis shows that acetone is a polar molecule due to the electronegativity of oxygen. The video concludes by identifying the presence of dipole-dipole interactions and London dispersion forces in acetone, with dipole-dipole being the stronger force.

What is the first step in analyzing the intermolecular forces in acetone?
