The hydrophilic end is 'water-loving' and forms chemical bonds with water and the hydrophobic end is 'water-hating' and forms chemical bonds with oil. This means that a liquid is joint together and can't move apart eg. mayonnaise

the hydrophilic part would be able to dissolve in water and the hydrophobic part wouldn't be able to dissolve in water but may dissolve in something else and then be able to allow the two liquids to mix.

Both answers are correct - a way I remember it is the hydrophobic end has a PHOBIA of hydro (water) , dyou get it?? the philic must be the opposite so likes the water :)
