Question

Which pat of a detergent molecule allows it to dissolve in water? which part allows it to dissolve substances?

Answer 1

Its hydrophilic part makes it water-soluble.

If the substance it solves is hydrophilic too it`s the same part that dissolves it. A lipophilic substance is dissolved by the lipophilic end.

The detergents with these properties is called  'surfactant' - a blend of "surface acting agent".
