WebMar 19, 2016 · The dipoles line up, positive to negative. 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. WebIn addition, the evolution of the dipole moment (Fig. 2) indicates that most of the electronic rearrangements take place within the transition state region, where the p-bond of ethylene is ...
WebEthylene glycol, $\mathrm{HOCH}_{2} \mathrm{CH}_{2} \mathrm{OH}$, has zero dipole moment even though carbon-oxygen bonds are strongly polar and oxygen has two lone-pairs of electrons. Explain. Answer. Due to the symmetry of the molecule. View Answer. ... so they tells ethylene glycol has a zero diploma, even though the carpet oxygen bonds … WebThis problem has been solved: Problem 5P. Chapter. CH2. Problem. 5P. Ethylene glycol, HOCH 2 CH 2 OH, may look nonpolar when drawn, but an internal hydrogen bond results in an electric dipole moment. Explain.
WebAug 11, 2024 · Molecular dynamics simulations show that the dipole moment magnitude of a small, yet conformationally rich molecule, ethylene glycol, increases upon its dilution …
