WebMethanol, ethanol, n -propyl alcohol, isopropyl alcohol, and t - butyl alcohol are all miscible with water. Alcohols with higher molecular weights tend to be less water-soluble, because the hydrocarbon part of the molecule, which is hydrophobic (“water-hating”), is larger with increased molecular weight.

Web1 apr. 2024 · 1. This is kind of an extreme case. Anhydrous ethanol and hexane are "just barely miscible"; the next step up in polarity (anhydrous methanol) is not miscible with hexane in all proportions. Furthermore, 4% water represents a significant amount of "contamination" with the least miscible common solvent. Even non-anhydrous solvents …
