  • $\begingroup$ @Mithoron it doesn't actually, my doubt is regarding the effect of H bonding on steam volatility, not the process itself. thanks though! :) $\endgroup$

  • $\begingroup$ Intramolecular H-bonding decreases availability for intermolecular H-bonding and general polar bond interactions, making the molecule effectively less polar and more volatile. $\endgroup$

  • $\begingroup$ @Poutnik That makes sense - thanks! I was curious as to how that'd explain the higher boiling point of picric acid when compared to p-nitrophenol? I'd imagine picric acid to undergo intramolecular H bonding and thus, have a lower b.p. and greater volatility. $\endgroup$

  • $\begingroup$ Picric acid has a much large molecular weight, 229 vs 139 g/mol. That's enough to justify the difference, but that's just one factor. The example of intramolecular H bonding illustrates the potential importance of this effect but it is only another of many factors. $\endgroup$

  • $\begingroup$ I think it kinda does, you just didn't see it. H-bonding is like last thing that's important, you need to know basics first - why it does anything, which still is not that much. $\endgroup$
