<p>4-Cyanopyridine is an organic compound with the chemical formula (CN)N. It is a white solid that is soluble in water and polar solvents. When exposed to hydrochloric acid, 4-cyanopyridine undergoes a reaction that converts it to picolinic acid. This reaction proceeds through a mechanism in which the nucleophilic hydroxyl group of 4-cyanopyridine attacks the protonated nitrogen atom of hydrochloric acid. The resulting intermediate then loses a proton and becomes picolinic acid. Kinetic data on this reaction has been obtained from UV-vis spectroscopy, X-ray diffraction, and mass spectrometry experiments. The crystal structures of the bound form of 4-cyanopyridine and its quinoline derivatives have also been determined by x-ray crystallography.</p>
