| Feb 4, 2021 at 18:02 | comment | added | Eric McGhee | I have edited the question to loosen language on the origin of the forces cited in the final paragraph as comments have pointed out important notes on resulting attraction forces in hydrophobic interactions. | |

| Feb 4, 2021 at 16:21 | comment | added | Eric McGhee | An ideal answer would identify the questions shortcomings, discuss these shortcomings, but also recognize and identify ranges of forces in measurable hydrophobic interactions. I think the comments so far have been extremely useful and valid, but being bogged down by these characteristics to the point where an answer is unachievable I don't think is productive. | |
| Feb 4, 2021 at 11:45 | comment | added | Buck Thorn♦ | The type of "force" in question does not have the classical meaning as "derivative (or gradient) of energy wrt position". This is what makes providing an answer far from trivial. Say you establish that the free energy of two states of your polymer in solution differ by some amount. What do you use as "distance" to compute a force? | |
| Feb 4, 2021 at 2:36 | comment | added | Eric McGhee | I have edited the question to reflect my above comment, as it might clear up what i mean and it provides an example | |

| Feb 4, 2021 at 2:33 | comment | added | Eric McGhee | hydrophobic interactions result from the hydrophobic effect and manifest in measurable attractive forces. the attractive force (per interaction) apparently depends on a lot of things, which is the basis of my question. induced dipoles are not required in hydrophobic interactions but can be another sort of interaction in a molecule. for example, the Polyhydroxyethylmethacrylate (pHEMA) backbone has dipole induced interactions, hydrophobic interactions, and hydrogen bonding; each of these interactions being identifiable in molecular position on the backbone (hydroxyl groups being hydrophobic). | |
| Feb 3, 2021 at 19:35 | comment | added | Mithoron | Well, I think there's a need for clarification - so-called hydrophobic effect in more of a phenomenon then force. There are obviously various interactions between induced dipoles, quadrupoles etc. but do you ask about them, then? | |
| Feb 3, 2021 at 15:39 | comment | added | Eric McGhee | I refer my information from a text book titled Intermolecular and Surface Forces; Israelachvili 3rd edition. I think your comments have been a bit patronizing, and if you refer to the question i say hydrophobic interactions and use quotations around "hydrophobic force". i realize this is not perfect, but it is a phenomena despite the etropic underpinnings. | |

| Feb 2, 2021 at 18:32 | comment | added | Buck Thorn♦ | You may have success if you look into surface tension and consider the area of the hydrophobic interfaces you are interested in. | |

| Feb 2, 2021 at 17:29 | comment | added | Eric McGhee | "The hydrophobic force describes the attraction between water-hating molecules (and surfaces) that draws them together, causing aggregation, phase separation, protein folding and many other inherent physical phenomena" it is not a fundamental force of nature, but it is a widely recognized intermolecular force. | |
| Feb 2, 2021 at 17:15 | comment | added | Mithoron | With this not being an actual force you can have some trouble here... | |
