Haloalkanes and Haloarenes question

2020 · Q91

NEETChemistryHaloalkanes and HaloarenesMCQ+4 / −1
Which of the following alkane cannot be made in good yield by Wurtz reaction?
  1. A
    2, 3-Dimethylbutane
  2. B
    n-Heptane
  3. C
    n-Butane
  4. D
    n-Hexane
View written solutionFree

Correct answer: B

Wurtz reaction is used to prepare symmetrical alkanes like

R1−-− X + 2Na + X−-− R1→Dry  ether\xrightarrow{Dry\;ether} Dryether​

R1−-−R1 + R1−-− R2 + R2−-− R2 + 2NaX

Using Wurtz reaction, n-Heptane can not be produced in good production because it is unsymmetrical alkane.
