Here's a taster:

Smaller Aldehydes and Ketones are soluble in water
because the lone electron pairs on the oxygen in the
carbonyl group form hydrogen bonds with the hydrogen
in the water molecules. As the chain length increases,
they become less soluble because the hydrocarbon `tail'
gets in the way.
· The longer the molecule the higher the boiling point
because there is a larger surface area and stronger
intermolecular forces between molecules.…read more
