Octane number can be changed by:

A

Isomerisation

B

Alkylation

C

Cyclisation

D

All of these

Text Solution

Verified by Experts

The correct Answer is:
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.
