MCQ
Octane number can be changed by
- AIsomerisation
- BAlkylation
- CCyclisation
- ✓All of these
✓
Answer
Correct option: D.
All of these
d
(d) The octane numbers of Fuel can be improved by increasing the percentage of branched chain alkanes, alkenes and aromatic hydrocarbon. Thus octane number can be changed by isomerisation (reforming), alkylation and aromatisation (cyclisation) etc.
