WebAlcohols can also form hydrogen bonds with water, so small alcohols are water-soluble. The smallest alcohols, methanol (CH 3 OH) and ethanol (CH 3 CH 2 OH), are completely soluble in water in any proportions. As the hydrocarbon part of an alcohol gets larger, the alcohol becomes less water soluble and more soluble in nonpolar solvents. Websoluble alcohols. Lucas reagent is a mixture of concentrated hydrochloric acid and zinc chloride. Zinc chloride is a Lewis acid, which when added to hydrochloric acid makes it even more acidic. Water soluble tertiary alcohols react with Lucas reagent almost immediately to form an alkyl chloride which is insoluble in the aqueous solution.
