Which of the following will not be soluble in sodium hydrogen carbonate ?

  • 2,4,6 trinitrophenol

  • Benzoic acid

  • o-nitrophenol

  • Benzenesulphonic acid

Solution

C.

o-nitrophenol


While 2,4,6-trinitrophenol, benzoic acid and benzene sulphonic acid are soluble in NaHCO3.This reaction is possible in the forward direction if acid is more acidic than H2CO3.o-nitrophenol is less acidic than H2CO3.Hence, it is not soluble in sodium hydrogen carbonate.
