Question

What is the correct assignment of the names of the following aromatic heterocycles? 
A)I = pyridine; II = pyrimidine; III = furan 
B)I = pyrimidine; II =pyrrole; III = furan 
C)I = pyridine; II = pyrrole; III = furan 
D)I = pyrimidine; II = pyrrole; III = tetrahydrofuran

Quizplus · Accepted Answer

I is pyridine based on the presence of a nitrogen atom in the ring.
III is furan based on the presence of an oxygen atom in the ring.
II is pyrrole based on the presence of a nitrogen atom in the ring and a double bond between two carbons, which is characteristic of pyrrole.
