Which of the following compounds will show retention in configuration on nucleophile substitution by OH - ion ?

Correct answer

Step-by-step solution

Option 1,2 and 3 have chiral carbon in which inversion of configuration takes place during S N 2 reaction but 4 th option has achiral carbon associated with halogen group so it will show retention after substitution reaction.
