Question:

Treatment of 3, 5-dimethylphenol with dilute nitric acid, followed by steam distillation of the reaction mixture, gave a compound A (C8H9NO3, mp 66°C) in 36% yield. The nonvolatile residue from the steam distillation gave a compound B (C8H9NO3, mp 108°C) in 25% yield on extraction with chloroform. Identify compounds A and B.
