Q135 / 200 · MHT CET - Medical 2026 (24 April Shift 2) · Chemistry
Which of the following reactions can convert chlorobenzene into toluene?
- AWurtz reaction
- BFittig reaction
- Correct answerCWurtz-Fittig reaction
- DGrignard reaction
Solution
Chlorobenzene is an aryl halide and toluene is an alkylarene (methylbenzene).
The reaction of an aryl halide with an alkyl halide in the presence of sodium metal and dry ether to form an alkylbenzene is known as the Wurtz-Fittig reaction.
$C_6H_5Cl + 2Na + CH_3Cl \xrightarrow{\text{dry ether}} C_6H_5CH_3 + 2NaCl$
Answer: Wurtz-Fittig reaction
The reaction of an aryl halide with an alkyl halide in the presence of sodium metal and dry ether to form an alkylbenzene is known as the Wurtz-Fittig reaction.
$C_6H_5Cl + 2Na + CH_3Cl \xrightarrow{\text{dry ether}} C_6H_5CH_3 + 2NaCl$
Answer: Wurtz-Fittig reaction
Hence, the correct answer is option: 'C'.
