They will have the strongest intermolecular forces. (strongest) 2. What is the strongest intermolecular force present in SO 2? ! 8. Basically, this strong intermolecular force is due to a strong dipole-dipole force as described above, plus the fact that the F, O, and N lone pairs are able to reach in closer to the hydrogen atom on another molecule. c) hydrogen bonding. The intermolecular forces are responsible for: holding molecules close together. Which substance below will require the most heat energy to enter the gas phase? 1. ion dipole, 2. hydrogen bonding, 3. dipole-dipole, 4. dispersion, 5. none B) Which molecule/compound has dispersion forces as its strongest intermolecular force? Well, it certainly does NOT have hydrogen bonding …. Dipole-dipole attractions result from the electrostatic attraction of the partial negative end of one dipolar molecule for the partial positive end of another. London dispersion forces. Could you explain or solve this problem? Learn this topic by watching Intermolecular Forces Concept Videos. Hydrogen bonding. Types of intermolecular forces (IMF), strongest to weakest: The stronger the IMFs, the higher the melting and boiling point of the compound, because you have to overcome the IMF in order to separate the molecules going from solid à liquid or liquid à gas. For each of the following pairs of elements, determine whether the compound is ionic, covalent, or metallic. (EN Values: S = 2.5; O = 3.5) A) Dispersion forces (London dispersion) B) Dipole-Dipole force. London dispersion forces occurs in all bonds, as it's a temperorary attraction force when electrons in an atom occupy positions that form temporary dipoles. Google Classroom Facebook Twitter. Expert Answer . This makes it the strongest intermolecular force because the charge of an ion is always much greater than the charge of a dipole. The attractive forces between ions is much greater than the attractive forces between molecules. In contrast, intramolecular forces act within molecules. cos’ it ain’t got no hydrogens…. A.
