Expert Solution

The intermolecular force is very important for solubility

The stronger the intermolecular forces between solute

molecule and solvent molecule, the greater the solubility of the solute in the solvent.

• Polar molecules are soluble in polar solvents (Predominant intermolecular force is

dipole-dipole attraction between polar solute molecule and polar solvent molecule).

• Nonpolar molecules are soluble in nonpolar solvents (Predominant intermolecular

force is London dispersion attraction between nonpolar solute molecule and

nonpolar solvent molecule).

• Polar molecules and nonpolar molecules do not mix.

Trends

1. Between two polar molecules, the molecule with the smaller hydrocarbon portion

(or the larger polar portion) is more soluble in water.

CH3CH2OH Soluble in water

CH3CH3CH3CH3CH3CH2OH Insoluble in water

CH2(OH)CH(OH)CH(OH)CH(OH)CH(OH)CH2OH Soluble in water. Large but many OHs

that can hydrogen bond with water.

2. If completely nonpolar, insoluble in water (and soluble in nonpolar solvents).

CH3CH3CH3CH3CH3CH3 Insoluble in water
