The S N 2 reaction involves back-side attack and therefore results in a "Walden Inversion." For which one of the substrates shown would you be able to demonstrate that such back-side attack with "Walden Inversion" has infact occurred?

Options

  1. A1-bromopropane
  2. B2-bromobutane
  3. C3-bromopentane
  4. DMethyl bromide

Correct answer

B. 2-bromobutane

Step-by-step solution

To observe inversion, the substitution must occur at a chiral center.
