SUMMARY

Heptanoic acid is more soluble in water than 1-octanol due to its ability to form stronger hydrogen bonds. The discussion highlights that compounds with fewer than five carbon atoms, such as alcohols, ethers, and epoxides, exhibit water solubility because of their oxygen atoms facilitating hydrogen bonding. In contrast, compounds with more than five carbon atoms, like 1-octanol, become less soluble due to the dominance of their non-polar alkyl portions. The conclusion is that heptanoic acid's structure allows for greater solubility compared to 1-octanol.

Homework Statement


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

Homework Equations


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.
 
Physics news on Phys.org
"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.
