interactions Classifying and Understanding Intermolecular Forces The 115 Intermolecular Force Worksheet Key likely covers the three primary types of intermolecular forces London Dispersion Forces LDFs These are the weakest IMFs arising from temporary fluctuations in electron distribution creating temporary dipoles The strength of LDFs increases with the size and complexity of the molecule A larger surface area generally results in greater induced dipole interactions DipoleDipole Interactions These forces occur between polar molecules which possess permanent dipoles due to differences in electronegativity between bonded atoms The stronger the dipole moment the stronger the interaction Polarity is directly related to molecule shape and the electronegativity of its constituent atoms Hydrogen Bonding A special type of dipoledipole interaction hydrogen bonding occurs when hydrogen is bonded to a highly electronegative atom such as nitrogen oxygen or fluorine The high electronegativity creates a strong dipole resulting in strong attractions between the hydrogen atom of one molecule and the highly electronegative atom of another Hydrogen bonding is significantly stronger than other dipoledipole forces thus exhibiting notable effects on physical properties Analyzing the Worksheet Key Implications and Applications By examining the examples and answers within
