The IUPAC name of pyridines is__________?
Correct answer: B. Azine
- A. Azolo
- B. Azine
- C. Azolidins
- D. Diazine
Explanation
Pyridine belongs to the azine class of six-membered aromatic nitrogen heterocycles, and “azine” is the expected name among these choices. “Diazine” is the likely alternative, but diazines contain two nitrogen atoms in the ring, whereas pyridine contains only one.

About Classification of Organic Compounds
Organic compounds are classified by carbon skeleton into open-chain, branched-chain and cyclic compounds, including homocyclic and heterocyclic types. The classification also uses functional groups to distinguish hydrocarbons, halo compounds, alcohols, aldehydes, ketones, carboxylic acids and their derivatives, which is different from naming compounds by IUPAC rules.
