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 \(773 \mathrm{~K}\)
- B \(\mathrm{Mo}_2 \mathrm{O}_3, 773 \mathrm{~K}, 10-20 \mathrm{~atm}\)
- C Anhyd. \(\mathrm{AlCl}_3\), conc. \(\mathrm{HCl}, \Delta\)
- D \(\mathrm{Cu}, 523 \mathrm{~K}, 100 \mathrm{~atm}\)
Answer & Solution
Correct Answer
(B) \(\mathrm{Mo}_2 \mathrm{O}_3, 773 \mathrm{~K}, 10-20 \mathrm{~atm}\)
Step-by-step Solution
Detailed explanation
Alkane with six or more C-atoms, when heated under pressure in the presence of a catalyst \(\mathrm{Mo}_2 \mathrm{O}_3\) at \(773 \mathrm{~K}\) at \(10-20 \mathrm{~atm}\). First cyclise and then aromatise to give benzene.
