Solution
The correct statements regarding pyrimidine are:
- Pyrimidine has a six-membered ring.
- Pyrimidine has nitrogen atoms at positions 1 and 3 of the ring.
- The lone pairs of electrons in pyrimidine all participate in resonance delocalization.
The statement that pyrimidine has a five-membered ring is not true. Pyrimidine, in fact, has a six-membered ring with two nitrogen atoms.
