In the analysis that follows the activity, they will relate IMFs (including hydrogen bonding) to physical properties (boiling point and solubility). 5. the forces created by the unequal distribution of charge result in varying degrees of attraction between molecules (14) = INTERMOLECULAR. The forces that hold molecules together in the liquid and solid states are called intermolecular forces. Instructional Objectives. 1) type of chemical bond, typically between macromolecules, that does not involve the sharing of pairs of electrons, but rather involves more dispersed variations of electromagnetic interactions. Among other things, intermolecular forces are important to hydrophilic (water-loving) and hydrophobic (water-hating) interactions. In order to form a solution, the solute must be surrounded, or solvated, by the solvent. H-bonds can from between an H on a(n) F, O, or N on one molecule, and a partially negative F, O, or N on another molecule. Polar molecules will be attracted to each other by either hydrogen bonding or dipole-dipole interactions. 4 - Methane: has only very weak London dispersion forces (lowest b.p. This type if intermolecular force is called a hydrogen bond (H-bond). Solubility and Intermolecular Forces . Effects of Intermolecular Forces: The strength of intermolecular forces present in a substance is related to the boiling point and melting point of the substance. Favourite answer Remember the rule of solubility: If force between solute-solvent is greater than the force between solute-solute molecules, than the substance is soluble. 7) sometimes used as a synonym for the totality of non-covalent forces which act between stable molecules.
