Identify the product X obtained in following reaction CH ₃- ( CH ₂ )₄- CH ₃ Cr ₂ O ₃ 773 ~K , 10-20 ~atm X

Options

  1. ACH ₃- CH = CH - CH ₃+ CH ₂= CH ₂+ H ₂
  2. B2 CH ₃- CH = CH ₂+ H ₂
  3. CC ₆ H ₆+4 H ₂
  4. DCH ₃- ( CH ₂ )₃- CH = CH ₂+ H ₂

Correct answer

C. C ₆ H ₆+4 H ₂

Step-by-step solution

Higher alkane with more than 5 carbon atom undergoes cyclization to form benzene in presence of Cr ₂ O ₃ under 10 to 20 ~atm pressure at 773 ~K .
