Concept explainers
Interpretation:
The two nitrogen atoms in nicotine that is converted into salts by the reaction with 1 mol of HCl should be identified. A structural formula of the salt should also be determined.
Concept Introduction:
Nicotine is an alkaloid containing pyridine and a pyrrolidine nitrogenous ring. Nicotine reacts with hydrochloric acid and forms water-soluble salt.
Nicotine is a dibasic acid because it contains two nitrogen atoms in its structure. There are two rings, pyridine and pyrrolidine, present in the nicotine molecule. The pKa value of pyridine ring and pyrrolidine ring is 3.12 and 8.02 respectively.
The structural formulas are as below:
Nicotine.
