WebThe solubility of alcohol molecules in water follows an interesting pattern. Smaller alcohol molecules tend to be more soluble than larger alcohol molecules. While small alcohol molecules like methanol and ethanol are completely miscible in water, alcohol molecules larger than n -octanol (C 8 H 17 OH) tend not to be soluble in water at all. ethanol http://delloyd.50megs.com/MOBILE/immiscible.html

WebSolubility of alcohols is therefore determined by the stronger of the two forces. Because of the strength of the attraction of the OH group, first three alcohols (methanol, ethanol and propanol) are completely miscible. They dissolve in water in any amount. Starting with the four-carbon butanol the solubility of alcohols is starting to decrease.
