Does ethanol have a high surface tension? Ethyl alcohol has some hydrogen-bonding, but one side of it is a hydrocarbon ( CH bonds), so the hydrogen-bonding in the big picture is not nearly as prominent. Therefore, since water molecules on a liquid surface are harder to push down on the surface tension is higher for […]
