pyridine on hydrogenetion gives​

Answer 1

Answer:

Hydrogenation and reduction

Piperidine is produced by hydrogenation of pyridine with a nickel-, cobalt-, or ruthenium-based catalyst at elevated temperatures. The hydrogenation of pyridine to piperidine releases 193.8 kJ·mol−1, which is slightly less than the energy of the hydrogenation of benzene (205.3 kJ·mol−1).
