(a) Draw the anti and gauche conformations for ethylene glycol ( HOCH 2 CH 2 OH ) . (b) Ethylene glycol is unusual in that the gauche conformation is more stable than the anti conformation. Offer an explanation.
(a) Draw the anti and gauche conformations for ethylene glycol ( HOCH 2 CH 2 OH ) . (b) Ethylene glycol is unusual in that the gauche conformation is more stable than the anti conformation. Offer an explanation.
Solution Summary: The author explains that the anti and gauche conformations for ethylene glycol are shown in Figure 2.
