Water solubles have poles (partial positive or partial negative ends) which being attracted by the opposite poles of water (OH- & H+ respectively) causes the solution. Hydrophobic substances have no such poles.
Phospholipids are insoluble in water since they are fats. Think of it this way...If you were to put a hunk of fat into a beaker of water it wont dissolve.
Because they are nonpolar
