What are X and Y respectively in the following reaction sequence?

Options

  1. AFeCl ₃, 773 ~K , 10-20 ~atm ;
  2. BMo ₂ O ₃, 770 ~K
  3. CAlCl ₃, , 10-20 ~atm ;
  4. DCr ₂ O ₃, 773 ~K , 10-20 ~atm

Correct answer

D. Cr ₂ O ₃, 773 ~K , 10-20 ~atm

Step-by-step solution

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 or reforming.
