    Compound ' PP ' on nitration with dil. HNO3HNO_{3} yields two isomers (a) and (b). These isomers can be separated by steam distillation. Isomers (a) and (b) show the intramolecular and intermolecular hydrogen bonding respectively. Compound (P)(P) on reaction with conc. HNO3HNO_{3} yields a yellow compound ' CC ', a strong acid. The number of oxygen atoms is present in compound ' CC '
