Octane number can be changed by:

A

(a) Alkylation

B

(b) Cyclisation

C

(c) Isomerisation

D

(d) All of the these

Text Solution

Verified by Experts

The correct Answer is:
D
All the three reactions, i.e., alkylation, cyclisation, and isomerisation convert straight-chain hydrocarbons to branched-chain or cyclic compounds, which changes the percentage of straight-chain hydrocarbon. Hence, the octane number is changed.
