Question

Which heterocyclic rings are present in nicotine?

• A. \( \text{Pyrimidine and Pyrrole} \)
• B. \( \text{Pyridine and Pyrrolidine} \)
• C. \( \text{Pyrimidine and Imidazole} \)
• D. \( \text{Piperidine and Pyrrolidine} \)

Hint:

Nicotine’s heterocyclic rings influence its pharmacological effects, including addiction and neurotransmitter modulation.

Answer 1

The Correct Option is B

Nicotine contains two heterocyclic rings: pyridine and pyrrolidine. The pyridine ring contributes to its neuroactive properties, while the pyrrolidine ring affects its solubility and binding to receptors. These structural components play a crucial role in nicotine’s interaction with the nervous system.
