Alcohol solubility

Solubility 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 After the 7-carbon heptanol alcohols are
