We’re being asked to explain the observed trend in terms of intermolecular forces based on the miscibility of the alcohols.
miscible → they will mix and will form a homogeneous mixture
immiscible → they will not mix and will form a heterogeneous mixture
We’re going to use the theory “like” dissolving “like” which states that the solvent can only completely dissolve the solute if they share similar polarity.
• Therefore, a pure solvent with similar polarity can successfully dissolve a solute to create a solution.
|Alcohol||Solubility in H2O (mol alcohol/100 g H2O)||Solubility in Hexane (C6H14) (mol alcohol/100 g C6H14)|
Consider the table listing the solubilities of several alcohols in water and in hexane. Explain the observed trend in terms of intermolecular forces.
