Question

Aromatization in alkane can be brought by using:

• A. $A{l}_2{O}_3$
• B. $F{e}_2{O}_3$
• C. $C{r}_2{O}_3/A{l}_2{O}_3$ at ${600}^{0}C$
• D. Conc. $H_{2}S{O}_4$

Answer 1

The correct option is C $C{r}_2{O}_3/A{l}_2{O}_3$ at ${600}^{0}C$

Aromatization in alkane can be brought by using $C{r}_2{O}_3/A{l}_2{O}_3$ at ${600}^{0}C$.

This process is known as reforming.

In this reaction, one hydrogen atom is removed from each terminal carbon atom of n-hexane to form cyclohexane. This is cyclization reaction.

This is followed by the removal of three hydrogen molecules to form benzene. This is aromatization reaction.

Option C is correct.
