Which of the following statements are correct about the mechanism of this reaction ?

Options

A. A carbocation will be formed as an intermediate in the reaction
B. `OH^(-)` will attach the substrate (ii) from one side and `Cl^(-)` will leave it simultaneously from other side
C. An unstable intermediate will be formed in which `OH^(-)` and `Cl^(-)` will be attached by weak bonds
D. Reactions proceeds through `S_(N)1` mechanism

Answer

A, D

Explanation

The reactant involved in above reaction is secondary alkyl halide. This `2^(@)` alkyl halide contain bulky group thats why it follow `S_(N)1` mechanism instead of `S_(N^(2))` mechanism, a stable carbocation will be formed as an intermediate. It is further attacked by `HO^(-)` nucleophile
