Which statement is true with respect to an SN2 reaction?
Correct answer: B. A good leaving group is a weak base
- A. A good leaving group is a strong base
- B. A good leaving group is a weak base
- C. A leaving group must be negatively charged
- D. A leaving group must be a halide
Explanation
A good leaving group is indeed a weak base, as it is easily replaceable by a stronger base and can be easily removed.

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.
