Question

Propene on reaction with reagent (A) gave \(X\) as major product. \(X\) undergoes Wurtz reaction to give \(Y\). In the presence of (B) at \(773\,\mathrm{K}\) and \(10{-}20\,\mathrm{atm}\) pressure, \(Y\) undergoes aromatization. It also undergoes isomerisation in the presence of (C). What are \(A\), \(B\), \(C\) respectively?

• A. \(\mathrm{HBr;\ anhyd.\ AlCl_3;\ V_2O_5}\)
• B. \(\mathrm{HCl;\ MoO_3;\ AlCl_3/HCl}\)
• C. \(\mathrm{HBr/(C_6H_5CO)_2O_2;\ Cr_2O_3;\ anhyd.\ AlCl_3/HCl}\)
• D. \(\mathrm{HBr/(C_6H_5CO)_2O_2;\ AlCl_3;\ CrO_3}\)

Hint:

Remember: \[ \boxed{ \mathrm{HBr + peroxide} \Rightarrow \text{Anti-Markovnikov addition} } \] \[ \boxed{ \mathrm{Cr_2O_3} \Rightarrow \text{Aromatization catalyst} } \] \[ \boxed{ \mathrm{AlCl_3/HCl} \Rightarrow \text{Isomerisation catalyst} } \]
