The alkyl bromide shown is treated with sodium metal in dry ether. Which structure is the main organic product?

  1. AStructure A
  2. BStructure B
  3. CStructure C
  4. DStructure D

Answer: C

The compound shown is 2-bromopropane. In the Wurtz reaction two alkyl groups couple, so two isopropyl groups join to give , 2,3-dimethylbutane. The skeleton of each alkyl group is retained, so straight-chain hexane and the other isomers are not formed.
