Problem

Rank these compounds by their expected solubility in Hexane C 6H14. Rank from most soluble to lease soluble.

i) C3H8

ii) CH3OH

iii) H2O

Solution

The rule that is used when it comes to solubility is that polar likes polar and non-polar likes non-polar. This just means that polar solutes are soluble in polar solvents and non-polar solutes are soluble in non-polar solvents.

The solvent, hexane $(C_{6}H_{14})$, is a non-polar solvent. It is composed of just carbons and hydrogens. That means that non-polar solutes will be soluble in it.

The first solute is $C_{3}H_{8}$. It is an alkane composed of just carbons and hydrogens, which makes it non-polar. That means it is soluble in hexane.
