WebMar 18, 2024 · In most compounds, there are large gaps in energies between the bonding orbitals (which are typically filled with electrons) and the antibonding orbitals (which are typically empty). Promotion of an electron from an occupied bonding orbital to an unoccupied antibonding orbital (a π → π * transition) usually requires 6 eV or more … WebDefine the three major intermolecular forces (IMF) that can exist in condensed phases: dipole-dipole, H-bonding, and dispersion (London, van der Waals, induced dipole- induced dipole, instantaneous dipole- instantaneous dipole). Predict the types of intermolecular forces that a compound can exhibit based on its structure.
