MCQ
The following reaction is described as
  • A
    ${S_{{E^2}}}$
  • B
    ${S_{{N^1}}}$
  • ${S_{{N^2}}}$
  • D
    ${S_{{N^0}}}$

Answer

Correct option: C.
${S_{{N^2}}}$
c
(c) In this reaction inversion of configuration takes place this is called optical inversion. It is an example of ${S_{{N^2}}}$ reaction (Bimolecular Nucleophillic Substitution).
