Options
- A. Biphenyl
- B. Toluene
- C. Phenol
- D. Benzene
Answer
A. Biphenyl
Step-by-step solution
The reaction of an aryl halide with sodium in the presence of dry ether to form a diaryl compound is known as the Fittig reaction. The chemical equation for the reaction is: 2 C _6 H _5 Cl + 2 Na dry ether C _6 H _5- C _6 H _5 + 2 NaCl From the stoichiometry of the reaction, 2 moles of chlorobenzene react with 2 moles of sodium to produce 1 mole of biphenyl. Therefore, 2n moles of chlorobenzene reacting with 2n moles of sodium will produce n moles of biphenyl. Answer: Biphenyl
