Name the endothermic reaction out of the following ?
Correct answer: C. Dehydrogeneration of Naphthene to produce aromatic
- A. Catalytic cracking
- B. Hydrocracking
- C. Dehydrogeneration of Naphthene to produce aromatic
- D. Catalytic polymerisation
Explanation
Dehydrogenation of naphthenes to aromatics is endothermic because hydrogen is removed and energy is required to form the aromatic structure. Catalytic cracking and polymerisation are commonly treated as exothermic overall, while hydrocracking releases heat through hydrogenation.
