Nowadays picric acid is prepared by treating phenol first
with concentrated sulphuric acid which converts it to
phenol-2,4-disulphonic acid, and then with concentrated nitric
acid to get 2,4,6-trinitrophenol Can you write the equations of
the reactions involved 2, 4, 6 - Trinitrophenol
is a strong acid due to
the presence of three
electron withdrawing
–NO2 groups which
facilitate the release of
hydrogen ion Rationalised 2023-24
