Triethylene glycol polarity
WebThe major by-products produced are the oligomers diethylene glycol, triethylene glycol, and tetraethylene glycol. The separation of these oligomers and water is an energy-intensive process. About 6.7 million tonnes are produced annually. ... Answer: Ethylene glycol comprises polar O-H groups. WebTriethylene glycol, HO (C 2 H 4 O) 3 H, is a colourless, odourless, non-volatile, and hygroscopic liquid. It is characterised by two hydroxyl groups along with two ether linkages, which contribute to its high water solubility, hygroscopicity, solvent properties and reactivity with many organic compounds.

Ethylene glycol, H OH 2C −CH 2OH has two polar hydroxyl groups, and the dipoles line up from molecule to molecule. This constitutes a potent intermolecular force, which accounts for the high boiling point of ethylene glycol, 197.3 ∘C, and also its viscosity. Answer link.
