Polymerisation__________________?
Correct answer: B. Causes olefins to combine with each other
- A. Produces i-octane from cracked gases containing i-butane and butene
- B. Causes olefins to combine with each other
- C. Causes aromatics to combine with each other
- D. Is aimed at producing lubricating oil
Explanation
Polymerisation joins olefin molecules together to form larger hydrocarbons, often improving the gasoline-range product yield. Producing isooctane from isobutane and butene is an alkylation reaction, not polymerisation.
