SN2 reactions can be best carried out with:
Correct answer: A. Primary alkyl halides
- A. Primary alkyl halides
- B. Secondary alkyl halides
- C. Tertiary alkyl halides
- D. Both primary and tertiary alkyl halides
Explanation
SN2 reactions has a nucleophilic attack on an electrophilic carbon. Resulting in a less steric congestion for this attack results in a faster reaction, meaning that SN2 reactions proceed fastest for primary carbons.

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.
