a part of Cengage Learning (e) the viscosity of isopropyl alcohol and glycerol (CH2OHCHOHCH,OH) (d) the odors of ethyl alcohol and glycerol 920gal 26 2animew oue nisnos 2. Aqueous solutions of isopropyl alcohol are commonly sold as rubbing alcohol. The boilling polnt of Isopropyl alcohol is 82.4 °C. It evaporates readily from the surface of the skin. Ethylene glycol (CH,OHCH,OH) is sold as antifreeze/antiboil. The boiling point of ethylene glycol is 198 °C. The mole- cular masses of isopropyl alcohol and ethylene glycol are similar. Provide an explanation for the observed difference in their boiling points. 3. Chromic acid oxidation is the basis of the Breathalyzer Test used by many police departments to delect etnyl alcohol in the breath of people suspected of driving under the influence. The amount of the n product is proportional to the amount of ethyl alcohol in the breath. Write structural formulas for the two oxidation products formed from ethyl alcohol. Name the oxidation products.
