Witryna3 lis 2016 · Acetone evaporate faster than ethanol because of Hydrogen Bond concept. Acetone being a ketone has no direct O-H bonds, hence lacks hydrogen bondigs. While ethanol being an alcohol does have a direct O-H connection. Hence, ethanol has intermolecular hydrogen bonds. Therefore, more stroger physical bonds have to be … Witryna5 cze 2014 · 1 Answer. The larger the intermolecular forces in a compound, the slower its evaporation rate. In order of decreasing strength, the important intermolecular forces in a compound are. They all depend on the fact that some parts of polar molecules have positive charges and other parts have negative charges.
