Measurement of ethylene glycol in serum or plasma for the evaluation of poisoning. Ethylene glycol is used as a solvent, in antifreeze, industrial humectant, and hydraulic brake fluids, and as a glycerin substitute in commercial products such as paints, lacquers, detergents, and cosmetics. It is colorless, odorless, but has a sweet taste.
Intermolecular attractive forces, collectively referred to as van der Waals forces, are responsible for the behavior of liquids and solids and are electrostatic in nature. Dipole-dipole attractions result from the electrostatic attraction of the partial negative end of one dipolar molecule for the partial positive end of another. .

Discussion: Intermolecular forces have strengths. Hydrogen bonds are the strongest followed by dipole-dipole forces. Ranking compounds from highest to lowest boiling points is accomplished using intermolecular forces. Ethanol, ethylene glycol, and glycerin have the highest boiling point followed...Intermolecular hydrogen bonding between glycol molecules gives these compounds boiling points which are higher than might otherwise have been expected; for example, ethylene glycol has a boiling point of 388.5 ° F (198 ° C). These forces are called intermolecular forces, and are in general much weaker than the intramolecular forces. We have, however, already discussed a very strong type of force that is responsible for much of chemistry - electrostatics.

Get free bonk io skinsEthylene glycol is widely used to inhibit the formation of natural gas clathrates (hydrates) in long multiphase pipelines that convey natural gas from remote gas fields to a gas processing facility. Ethylene glycol can be recovered from the natural gas and reused as an inhibitor after purification treatment that removes water and inorganic salts. The weaker the intermolecular forces in the liquid, the more easily molecules can escape and, therefore, the higher the vapor pressure at a given temperature. GIVE IT SOME THOUGHT. Which compound do you think is more volatile at 25 °C: CCl 4 or CBr 4? GO FIGURE. What is the vapor pressure of ethylene glycol at its normal boiling point? The intermolecular forces between molecules in the liquid state vary depending upon their chemical identities and result in corresponding variations in various physical properties. Cohesive forces between like molecules are responsible for a liquid’s viscosity (resistance to flow) and surface tension (elasticity of a liquid surface). Ethylene Glycol. Ethylene glycol is an organic compound with the formula₂. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations. It is an odorless, colorless, sweet-tasting, viscous liquid. Density: 1.11 g/cm³ Boiling point: 387.14°F (197.30°C) Chemical formula: C2H6O2

a This will also determine how strong the intermolecular forces are for this molecule. All of these are directly correlated to the strength of the intermolecular forces. Procedure: Surface TensionSurface tension is measured by the curvature of a drop of a substance. Surface tension is the resistance of a liquid surface to stretching. Three drops of different substances will be placed on a table. The substances are ethylene glycol, ethanol, and glycerin. Answer The ethylene glycol can form hydrogen bonds on both ends of the molecule resulting in much stronger intermolecular forces and a higher boiling point. Which of the following materials is likely to have (a) no dipole-dipole forces, but the largest London dispersion forces, (b) the largest dipole-dipole intermolecular forces: I2, He, H2S, H2Te. Intermolecular attractive forces, collectively referred to as van der Waals forces, are responsible for the behavior of liquids and solids and are electrostatic in nature. Dipole-dipole attractions result from the electrostatic attraction of the partial negative end of one dipolar molecule for the partial positive end of another.

Understanding their nature is of great scientific interest and relevant for a wide range of applications.The ethylene glycol either gains energy from the source (lake, ocean, water well) or dissipates heat to the sink, depending on whether the system is being used for heating or cooling. Pure ethylene glycol has a specific heat capacity about one half that of water. So, while providing freeze protection and an increased boiling point, ethylene glycol lowers the specific heat capacity of water mixtures relative to pure water.
