The cracking problem of fuel combustion can be avoided by:
Correct answer: D. All of the above
- A. Reforming
- B. Improving octane number
- C. Adding TEL
- D. All of the above
Explanation
Option D is correct because reforming, improving the octane number, and adding TEL are all methods that help reduce knocking and improve engine performance by increasing the octane number. Reforming and adding TEL directly increase the octane rating, leading to smoother fuel combustion. Option A only covers reforming, Option B focuses solely on octane number improvement, and Option C only mentions the use of TEL. Each method individually contributes to the solution, but all together, they comprehensively address the problem of cracking in fuel combustion.

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.
