InterviewSolution

1.	Octane number can be changed byA. IsomerisationB. AlkylationC. CyclisationD. All of these
Answer» Correct Answer - D The octane number 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.
