However a high bp can point to hydrogen bonding, which would mean favourable interactions with water. For propanon / propanal your approach was right but I'd argue that the keton is so miscible because the oxygen is in a symmetrical central position, whereas the aldehyde has a hydrophilic and a hydrophobic end - maybe there is more, surprised it would have such a strong effect with a 3C chain length (that two-tail effect is used in tensides / soaps, where the chain length is around 12-18 Cs) | |

| Jun 26, 2019 at 18:06 | comment | added | Buck Thorn♦ | By the way, the OP asks about the connection between the boiling point and solubility, not the melting point. | |

| Jun 26, 2019 at 15:20 | comment | added | LoschmidtsSchnitzel | Between solid solute and solvated solute. There is mechanical, thermal and chemical equilibrium and two distinct phases, so this is also a phase equilibrium | |
| Jun 26, 2019 at 14:40 | comment | added | Buck Thorn♦ | What do you mean with " phase equilibrium between a soluble compound C and water"? | |
