Which of the following compounds cannot be prepared singly by the Wurtz reaction?

  • A
    $\mathrm{C}_{2} \mathrm{H}_{6}$
  • Correct answer
    B
    $\left(\mathrm{CH}_{3}\right)_{2} \mathrm{CHCH}_{3}$
  • C
    $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{3}$
  • D
    All of the above can be prepared

Solution

If two different alkyl halides $\left(\mathrm{R}_{1}-\mathrm{X}\right.$ and $\left.\mathrm{R}_{2}-\mathrm{X}\right)$ are used, a mixture of three alkanes is obtained which is difficult to separate.

Hence, the correct answer is option: 'B'.
