Title: Solubility of C3F8
Post by: dorin1993 on December 23, 2012, 07:46:28 AM

Why isn't C3F8 soluble in water?
It can make hydrogen bonds with F (C3F8) and H (of H2O)

Is Hydrogen bonding , the only criteria to determine the solubility of a compound in water ? Also , can you analyze the dipole moment for C₃F₈ ?

Presumably this is like teflon, with the solubility of teflon in water = 0

Maybe we should go by the rule of the thumb 'like dissolves like' and go with dipole moment to check solubility. This seems to be a good question for thought. Although H-bonding is very much plausible, we don't see the substance dissolving in water. Maybe the microscopic observations we make aren't enough. The bulk probably matters more. Can someone comment on this? I may be way off
