Dehydrohalogenation of RX occurs in the presence of
Correct answer: A. An alcoholic base
- A. An alcoholic base
- B. An alcoholic acid
- C. An alcoholic salt
- D. An alcoholic Grignard reagent
Explanation
In alcoholic medium OH becomes strong base hence it attacks on β-H instead of replacing X from RX. Therefore, alkene is produced from RX by β-elImination reaction.
