Question

Both isopropyl alcohol, C3H8OH, and ethylene glycol, C2H6O2, are used as antifreeze. When equal masses of each are added to water, which, if either, will be more effective at preventing freezing? A. Isopropyl alcohol B. Ethylene glycol C. They will produce the same effect D. Neither, because they do not dissolve in water.

Answer 1

I believe the correct answer from the choices listed above is option B. When equal masses of each are added to water, ethylene glycol would be more effective. Ethylene glycol is the most widely used automotive cooling-systemantifreeze, although methanol, ethanol, isopropyl alcohol, and propylene glycol are also used.
Hope this answers the question. Have a nice day.
