The Correct Option is D
Solution and Explanation
Concept:
Conversion of straight-chain alkanes into aromatic hydrocarbons is called aromatization or dehydrocyclization.
This process is carried out using catalysts such as chromium oxide at high temperature.
Step 1: Write the transformation. \[ C_7H_{16} \rightarrow C_7H_8 +4H_2 \] This converts n-heptane into toluene.
Step 2: Identify the catalyst used. Industrial aromatization is carried out using: \[ Cr_2O_3 \] at high temperature and moderate pressure. Typical conditions are: \[ 773\,K \] and about \[ 10\,atm \]
Step 3: Compare with options. Only Option (D) provides the correct catalyst and conditions. Therefore, \[ \boxed{Cr_2O_3,\;773\,K,\;10\,atm} \]
