Which of the following alkenes does not undergo anti Markovnikov addition of HBr ?
  1. Propene
  2. 1 -Butene
  3. 2 -Butene
  4. 3-Methyl-2-Penten

Solution

But-2-ene i.e $\mathrm{CH}_3-\mathrm{HC}=\mathrm{CH}-\mathrm{CH}_3$ is the symmetrical alkene among the given alkenes. Hence anti-Markovnikov addition is not observed in But-2-ene.
