Question

Which one of the following methods is suitable to generate aromatic compound(s) from linear aliphatic saturated hydrocarbons with at least six carbon atoms?

• A. Heating at $773\, K$
• B. $Mp _{2} O _{3}, 773\, K , 10-20\, atm$
• C. Anhyd $. AlCl _{3}$, conc . $HCl$, $\Delta$
• D. $Cu , 523 K , 100\, atm$

Answer 1

Answer: (B)

Alkane with six or more $C$-atoms, when heated under pressure in the presence of a catalyst $Mo _{2} O _{3}$ at $773\, K$ at $10-20 \,atm$. First cyclise and then aromatise to give benzene.
