β-elimination reactions are due to:
Correct answer: B. Attack of the incoming nucleophile on beta hydrogen
- A. Attack of the incoming nucleophile on alpha hydrogen
- B. Attack of the incoming nucleophile on beta hydrogen
- C. Attack of the incoming nucleophile on beta carbon
- D. Attack of incoming nucleophiles on electrophilic carbon
Explanation
β-elimination reactions are due to attack of the incoming nucleophile on beta hydrogen. β-Elimination involves attack of strong base (e.g. OH-) on β-hydrogen.

About Alkyl Halides
Alkyl halides are named and related to their carbon-halogen structure, polarity and reactivity. The key reactions are nucleophilic substitution by SN1 and SN2 mechanisms and elimination by E1 and E2 mechanisms, including how substrate structure, nucleophile, base, solvent and temperature influence substitution versus elimination.
