WebDec 15, 2024 · 2.6.1 Intermolecular Forces. In Organic Chemistry, the understanding of physical properties of organic compounds, for instance boiling point (b.p.), molecular polarity and solubility, is very important. It provides us with helpful information about dealing with a substance in the proper way. Those physical properties are essentially determined ... WebAboutTranscript. Dipole–dipole forces occur between molecules with permanent dipoles (i.e., polar molecules). For molecules of similar size and mass, the strength of these forces increases with increasing polarity. Polar molecules can also induce dipoles in nonpolar molecules, resulting in dipole–induced dipole forces.

WebDec 27, 2013 · Intermolecular bonds are caused by the attractive forces between the negative end of one molecule and the positive end of another. A polar molecule has a positive end and a negative end. When two polar molecules are near each other, they arrange themselves so that the negative and positive ends line up and attract the two … WebMay 25, 2024 · The properties of liquids are intermediate between those of gases and solids, but are more similar to solids. In contrast to intramolecular forces, such as the covalent bonds that hold atoms together in molecules and polyatomic ions, intermolecular forces hold molecules together in a liquid or solid.Intermolecular forces are generally …
