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. WebIn aqueous solutions, phenols are weakly acidic and lower the pH of a solution. Sodium hydroxide can be used to fully deprotonate a phenol. Water soluble alcohols do not change the pH of the solution and are considered neutral.
