Answer
Diethyl ether is more soluble in water because the oxygen atom in it polarizes the small molecule, which allows the diethyl ether to dissolve in water. As water is also polar, the large dihexyl ether molecule does not dissolve, due to its large non-polar parts. As propane is non-polar, it is less soluble in water than diethyl ether.
