Octane rating of Gasoline can be increased by __________?
Correct answer: C. Reforming
- A. Refining
- B. Cracking
- C. Reforming
- D. None of These
Explanation
Catalytic reforming converts straight-chain hydrocarbons into branched, cyclic and aromatic hydrocarbons, which resist knocking and therefore have higher octane ratings. The likely wrong choice is cracking, which mainly changes large molecules into smaller ones and does not by itself describe the main octane-improvement process.

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.
