- D \(\mathrm{Cr}_2 \mathrm{O}_3, 773 \mathrm{~K}, 10-20 \mathrm{~atm}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{Cr}_2 \mathrm{O}_3, 773 \mathrm{~K}, 10-20 \mathrm{~atm}\)
Step-by-step Solution
Detailed explanation
n-Alkanes having six or more carbon atom on heating to 773 K at 10-20 atmospheric pressure in the pressure of oxides of vanadium molybedenum or chromium supported over alumina get dehydrogenated and cyclised to benzene and its homologous. The reaction is known as aromatization…
