  • Preparation of picric acid - Chemistry Stack Exchange
    The picric acid is an oil, that soon gets solid after one minute or two Throw the liquid away Half fill the tube with $\pu{10 mL}$ water Heat to $\pu{100°C}$: the picric acid gets dissolved Wait : nice yellow needles are produced in the tube by slow cooling It is picric acid, which can be filtered in case of necessity But don't do it
  • Why is picric acid not more steam volatile than p-nitrophenol, if . . .
    $\begingroup$ 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 That's enough to justify the difference, but that's just one factor
  • How to weight picric acid? - Chemistry Stack Exchange
    $\begingroup$ Only about 1–2% of picric acid would be actually dissolved in water at room temperature, so without consulting any literature sources I guess it would be enough to just distribute the dispersed substance on a surface and let it dry for a while $\endgroup$ –
  • organic chemistry - Why is picric acid more explosive than TNT . . .
    The structure and molar mass are very similar to TNT, but replacing the methyl group with a hydroxyl means the oxygen content of picric acid is higher While still overall oxygen-poor, the detonation proceeds with much less soot and hydrogen generation, meaning a more complete burn, a higher energy release, and consequently a greater explosive
  • Why is picric acid more acidic than carbonic acid?
    You've probably been told that hydroxyl groups (C-OH, present in alcohols and phenols) are weaker acids than carboxyl groups carboxylic acids, yet picric acid is a substituted phenol and is quite a bit more acidic than carbonic acid and simple carboxylic acids
  • organic chemistry - Why cant picric acid be made more acidic by adding . . .
    I understand that picric acid is acidic because of the $\ce{-NO2}$ electron withdrawing group, but why can't we add more of those on the meta positions to make it more acidic? Is it because that $\ce{-NO2}$ shows less -R effect when it is on that meta positions?
  • Is picric acid a very strong acid? - Chemistry Stack Exchange
    Picric acid has nitro groups in para and ortho positions, so it has great possibility to go for resonance, thus it is supposed to be a very good acid But a question arises! But a question arises! The $\ce{O}$ of $\ce{-OH}$ has intramolecular $\ce{H}$-bonding with ortho -nitro groups present on both sides
  • Potassium tert-butoxide reaction with chloroform and picric acid
    If potassium tert-butoxide is used in a solution of chloroform and and a strong protic acid like picric acid will the tert-butoxide ion react with picric acid or will it form a dichlorocarbene Mechanism for reactions will be much appreciated (This is most definitely NOT a homework question! I need to know this to solve my homework problems)
  • Picric Acid from Salicylic Acid - Chemistry Stack Exchange

  • What are bond lengths and angles for picric acid? [closed]
    The asymmetric unit in this structure contains two molecules of picric acids – with and without H-atoms Obviously, you need the one with the protons assigned Share
