Identify the Swarts reaction from the following:

Options

  1. AR - CH ₂- Br + Nal [ acetone ] dry R - CH ₂- I + NaBr
  2. B2 R - CH ₂- Br +2 Na [ ether ] dry R - ( CH ₂ )₂- R +2 NaBr
  3. C2 C ₆ H ₅ Cl +2 Na [ ether ] dry C ₆ H ₅- C ₆ H ₅+2 NaCl
  4. D2 R - CH ₂- Br + CoF ₂ 2 R - CH ₂- F + CoBr ₂

Correct answer

D. 2 R - CH ₂- Br + CoF ₂ 2 R - CH ₂- F + CoBr ₂

Step-by-step solution

The synthesis of alkyl flurorides is best accomplished by heating an alkyl chloride bromide in the presence of a metallic fluoride such as AgF ₂, HgF ₂ or SbF ₃ . The reaction is termed as Swarts reaction.
