In the following reaction,the product 'R' is \( : \boldsymbol{C a} \boldsymbol{C}_{2} \stackrel{\boldsymbol{H}_{2} \boldsymbol{O}}{\longrightarrow} \boldsymbol{P}_{\boldsymbol{t u b e}}^{h o t} \stackrel{i r o n}{\boldsymbol{Q}} \frac{C \boldsymbol{H}_{3} C l}{A \boldsymbol{l} C l_{3}} \boldsymbol{R} \)
- A. Chloro benzene
- B. benzene
- C. toluene
- D. anisole
Step-by-step solution
CaC2 reacts with H2O to give acetylene (P). Acetylene passed through a red hot iron tube undergoes cyclization to form benzene (Q). Benzene then undergoes Friedel-Crafts alkylation with CH3Cl in the presence of AlCl3 to yield toluene (R).
