The cracking method used to obtain better quality gasoline is:
Correct answer: B. B: Catalytic
- A. A: Thermal
- B. B: Catalytic
- C. C: Steam
- D. D: Radiations
Explanation
The correct answer is Catalytic cracking, which is a preferred method for producing higher quality gasoline. This process employs catalysts to facilitate the breakdown of larger hydrocarbon molecules into smaller, more valuable ones, enhancing the quality of the final product. In contrast, Thermal cracking generates lower quality fuels due to the absence of catalysts and the harsh conditions involved. Steam cracking, while effective for producing lighter hydrocarbons, does not specifically aim to improve gasoline production. Radiations do not play a significant role in the cracking processes used in the petroleum industry.

About Alkanes
Alkanes are saturated hydrocarbons containing only carbon-carbon and carbon-hydrogen single bonds, with the general formula CnH2n+2 for open chains. Their structure, isomerism, IUPAC nomenclature, physical properties, combustion, free-radical halogenation and conformations are covered, including the difference between substitution in alkanes and addition in unsaturated hydrocarbons.
