A diol is a chemical compound containing two hydroxyl groups (âOH groups). This pairing of functional groups is pervasive, and many subcategories have been identified. The most common industrial diol is ethylene glycol.Examples of diols in which the hydroxyl functional groups are more widely separated include 1,4-butanediol HOâ(CH 2) 4 âOH and bisphenol A, and propylene-1,3-diol, or beta propylene glycol, HOâCH 2 âCH 2 âCH 2 âOH.n general, organic geminal diols readily dehydrate to form a carbonyl group. For example, carbonic acid ((HO) 2 C=O) is unstable and has a tendency to convert to carbon dioxide (CO 2) and water (H 2 O). Nevertheless, in rare situations the chemical equilibrium is in favor of the geminal diol.
Dispersion forces are the only type of intermolecular forces experienced by nonpolar molecules. Dipole-dipole forces exist between polar molecules. Polar molecules have a permanent dipole, so the charges (notated as + (partial positive) and (partial negative) are separated from one another.n general, intermolecular forces are much weaker than the ionic and covalent bonds that hold together the atoms and ions in a compound. For example, about 40 kJ of energy are required to vaporize 18 grams of water moleculesâi.e., completely convert 18 grams of water to water vapor or steam.
