Methanol is soluble in water but insoluble in octane. Explain briefly.
Answer:
Solubility of a substance is its maximum amount that can be dissolved in a specified amount of solvent at a specified temperature. It depends
upon the nature of solute and solvent as well as temperature and pressure. In general, a solute dissolves in a solvent if the intermolecular interactions are similar in the two or we may say like dissolves like.
Like dissolves like means compounds with similar polarity will dissolve in compounds with similar polarity or electrical properties
Methanol and water both are polar and hydrogen bond forming molecules. Thus, they will form homogeneous solution. Whereas octane is non-polar molecule and will not form solution with methanol.
