An alkyl bromide (X) reacts with sodium in ether to form 4,5 -diethyl octane, the compound X is

Options

  1. ACH ₃ ( CH ₂ )₃ Br
  2. BCH ₃ ( CH ₂ )₅ Br
  3. CCH ₃ ( CH ₂ )₃ CH ( Br ) CH ₃
  4. DCH ₃- ( CH ₂ )₂- CH ( Br )- CH ₂- CH ₃

Correct answer

D. CH ₃- ( CH ₂ )₂- CH ( Br )- CH ₂- CH ₃

Step-by-step solution

Alkyl halides react with metallic Na in presence of dry ether to form symmetrical alkanes containing double the number of carbon atoms present in the alkyl halide. This reaction is called Wurtz reaction.
