Propanone is more
soluble in water compared to propane mainly because propanone cannot hydrogen
bond with themselves but can hydrogen bond with water molecules. One of
the slightly positive hydrogen atoms in a water molecule can be sufficiently attracted
to one of the lone pairs on the oxygen atom of propanone. In order for 3-hexanol to bond with water, the
van der Waals forces must be broken and also the stronger hydrogen bonds of
water molecules and it needs a great amount of energy.
