Question:
The catalyst used for the isomerisation of n-alkanes to branched chain alkanes is:
The catalyst used for the isomerisation of n-alkanes to branched chain alkanes is:
Show Hint
AlCl$_3$/HCl acts as an efficient catalyst in isomerization of alkanes, especially to increase fuel efficiency (octane rating).
Updated On: Jun 4, 2025
- Anhy. AlCl$_3$/HCl
- Mo$_2$O$_3$
- FeCl$_3$
- TiCl$_4$ + R$_3$Al
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Isomerization of n-alkanes to branched alkanes (to improve octane number in fuels) is catalyzed by Lewis acids like anhydrous AlCl$_3$ in the presence of HCl gas. This is a standard method in petrochemical industries.
