It is used to inactivate the influenza virus in … Which of the following conformers for ethylene glycol is the most stable? How can the gauche conformation of ethylene glycol be more stable than the anti conformation? Key Idea The conformation in which the heavier groups are present at maximum possible distances, so that the forces of repulsion get weak, is more stable. Aren't the bulk groups furthest apart in the anti conformation? and Inverse Proportions, Areas Which of the following conformers for ethylene glycol is most stable ? The most common catalysts consist of titanium(III) chloride, the so-called Ziegler–Natta catalysts. 000+ LIKES Both investigations report a hydrogen-bonded gauche form to be the most stable one. As you can see, in the anti-conformer, the two O H groups are at the greatest possible distance from one another. Cloudflare Ray ID: 6216aed16f5d36de The gauche conformation is stabilized by H-bonding. Check PSEB class 12 syllabus, exam pattern & preparation tips. Can you explain this answer? UP Board 2021 Class 10 Datesheet Released, Check Here. Most stable conformation of ethylene gycol is gauche conformation. The most stable conformation of ethylene glycol has the two hydroxyl groups opposite from one another. Staggered conformation of ethane is the most stable while eclipsed conformation is the least stable. 
due to intramolecular H-bonding gauche is most stable. eclipse, anti, gauche) of ethylene glycol is : Which of the following conformation of butane is most stable ? The Questions and Answers of The most stable conformation of ethylene glycol is:a)Antib)Gauchec)Partially eclipsedd)Gully eclipsedCorrect answer is option 'B'. Ethylene glycol … Your IP: 50.63.162.95 Confusion has arisen, because polyethylene glycol (a chemical used in antifreeze and personal care products like skin creams and toothpaste) is used in vaccines and is safe. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. View All. An extension of earlier ab initio calculations is reported which consists in a more detailed structure optimization of conformations investigated earlier, using the previously described as well as a more flexible basis set. I hope this helps :) The effect of the various conformations on metabolism of dihydrodiols to dihydrodiol epoxides is considered. More stable conformation of ethylene glycol is A)Eclipsed form B)staggered form C)Skew form D)None of these. As a theoretical analysis of the conformational equilibria of ethylene glycol, methoxyethanol and dimethoxyethane, the energy of each stable conformational isomer (rotamer) of these molecules was calculated for various temperatures and solvent dielectric constants. Gauche conformer will be most stable in case of ethylene glycol. – ron … Ethylene is a stable molecule that polymerizes only upon contact with catalysts. Antifreeze is typically made of ethylene glycol, which is unsafe. PEG has both polar and non-polar groups in its structure, which contribute to its solubility and properties in organic and aqueous solvents. The conversion is highly exothermic. NEET 2021 exam likely to be held twice a year for admission to MBBS, BDS, AYUSH and BVSc courses. Conformation, environment and reactivity of radicals in copolymerization of methyl methacrylate/ethylene glycol dimethacrylate Y. Tian, S. Zhu and A. E. Hamielec* Institute for Polymer Production Technology, Department of Chemical Engineering, IVIcMaster University, Hamilton, Ontario, Canada LSS 4L 7 D. B. Fulton and D. R. Eaton Department of Chemistry, McMaster University, … KEAM 2010. 12th. For nanocarriers with low protein affinity, we show that the interaction of nanocarriers with cells is mainly affected by the density, the molecular weight, and the conformation of polyethylene glycol (PEG) chains bound to the nanocarrier surface. Its most common use is as an automotive antifreeze. Check UP Board 10th date sheet 2021, admit card, result and other information. Another way to prevent getting this page in the future is to use Privacy Pass. • Eclipsed and Staggered/anti conformers are not the most stable.This is due to less torsional strain and less steric strain in gauche conformer as compared to eclipsed conformer. Try it now. This prevents h bonding to occur between the two oh groups, leading to a lower energy state and greater stability than the anti comformer. The most stable conformation for 1,2-ethanediol (ethylene glycol) is shown below. UP board class 10 exam 2021 will be held from 24th April to 10th May 2021.
