JEE Main levelSingle correct optionDifficulty 2 of 3hc170

Wurtz reaction of 2-bromopropane alone (sodium, dry ether) gives:

  1. AHexane
  2. B2-Methylpentane
  3. C2,3-Dimethylbutane
  4. D2,2-Dimethylbutane

Answer: C

Two groups join to form , which is 2,3-dimethylbutane. The other options contain carbon skeletons that cannot arise from simple dimerisation of the isopropyl group.
