What's more soluable in water?

[BlueScreenOD]

1. The problem statement, all variables and given/known data
Which compound would you expect to be more soluble in water: heptanoic acid or 1-octanol?

Which of the compounds has the greater solubility in water and why?
2-Propanone or 1-Propanol



2. Relevant equations



3. The attempt at a solution
I believe for the first question that the answer is heptanoic acid because it has increased hydrogen bonding. I think the second answer is alcohol for the same reason.

I have an exam tomorrow, so if anyone could clear this up I'd be very appreciative.

"alcohols, ethers and epoxides having less than or 5 carbon atoms are water soluble because they each have an oxygen atom capable of hydrogen bonding."

"alcohols, ethers and epoxides having more than 5 carbon atoms are insoluble because the non-polar alkyl portion is too large to dissolve in water"

Thanks for your reply Cronxeh. I know they're both soluble, but what I need to know is which is MORE soluble.
