Intermolecular Forces



Summary
The content provides an in-depth exploration of intermolecular forces, crucial for understanding boiling and melting points, essential concepts for the MCAT exam.
  • London dispersion forces involve induced dipoles and are size-dependent, affecting the boiling points of non-polar compounds.
  • Dipole-dipole interactions occur between polar molecules, influencing their state and boiling points, with an emphasis on the molecular structure's role in determining polarity.
  • Hydrogen bonding, the strongest intermolecular force, significantly raises the boiling points of compounds, especially those involving nitrogen, oxygen, and fluorine.
  • The size of a molecule can influence the relative strength of intermolecular forces, with larger molecules experiencing more pronounced London dispersion forces.
  • Ionic compounds have higher boiling and melting points than covalent compounds, a critical consideration for predicting boiling points on the MCAT.
