Question

Predict major product in the given reaction.

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

Substitution of halide group by hydroxyl group through nucleophilic substitution reaction is known as Dow's process.
This mechanism contains two steps:
1) Attack of nucleophile
2) Removal of leaving group


When EWG is at ortho position​ then negative charge on ortho position is stabilized​ by electron withdrawing group​.
When EWG is at para position​ then negative charge on para position is stabilized​ by electron withdrawing group​.
When EWG is at meta position​ then negative charge on meta position is not stabilized​ by electron withdrawing group​.
