Thanks for the useful link. I went now down to G and H.
Phenol reacts with nitric acid.
The molecule of G has two planes of symmetry (that of the molecule and an orthogonal one), while the plane of the molecule is the only element of symmetry for H. Starting with G, one can obtain paracetamol J via a two-stage process.
G should be the ortho isomer, while H should be the para isomer. Paracetamol has para -substituted groups, but G has ortho ones. Is this a mistake? The paracetamol should be obtained from H instead?
By reduction an amine is produced. Why will the amine group react with the anhydride, but not the hydroxy group?
