Differenciate between phenol and benzoic acid using bromine water

Phenol reacts with bromine in carbon disulphate at low temperature to give o-and p-bromophenol. .

Neutral FeCl3 test regents may be used to distinguish between phenol and benzoic acid as Phenol will give violet coloration but benzoic acid will not give coloration with neutral FeCl3.

* Aqueous bromine can only decolourise C=C double bonds in alkenes (with no ppt.) and phenols (with white ppt.). No thats not possible, bromine water can only decolourise alkenes not carboxylic acids. the C=O bond is nt broken at all.

hope it is helpful.

Phenol and Benzoic acid cannot be distinguished using Bromine water.

  • The difference between phenol and benzoic acid cannot be determined by the bromine water test, since phenol is alcohol while benzoic acid is an acid.
  • The bromine water test is used to test saturation, meaning it can be used to separate alkanes from alkenes or alkynes.
  • Sodium bicarbonate is the best way to tell the difference between an alcohol and an acid.
  • Acids give a brisk effervescence when they react with sodium bicarbonate, but alcohols do not.
