Let’s break down each option in turn and consider what is generally true for alcohols. Option 1: they generally have relatively low boiling points - This is not correct. Alcohols typically have relatively high boiling points compared to hydrocarbons of similar molecular weight because they can form hydrogen bonds between molecules. So the statement as written (generally low boiling points) is false. Option 2: they are moderately water soluble - This is often true for small to mid-sized alcohols.
