Solubility of organic compounds

DespicableMe

1. The problem statement, all variables and given/known data

Rank the solubilities of these organic compounds from lowest to highest:
Hydrocarbons, aldehydes, alcohols, carboxylic acid.


3. The attempt at a solution

I know that hydrocarbons is the lowest - it cannot form H bonds with itself nor can it form H bonds with water.

For the other 3, though, I'm not sure which one has a stronger solubility over the other two.
They are all soluble because they can form H-bonds with water even though they might not be able to form H bonds with itself (aldehydes).
All their solubilities fall as the length of their hydrocarbon chains increase, so I'm not sure how to rank the last 3.

What if something is ionized?

I'm not sure, they only asked us to rank those 3.

What acid does in water?
