Among the alkyl halides, which always follows SN2 mechanism:
Correct answer: A. Primary alkyl halides
- A. Primary alkyl halides
- B. Secondary alkyl halides
- C. Tertiary alkyl halides
- D. Both secondary and tertiary alkyl halides
Explanation
Since primary alkyl halide is least sterically hindered among primary, secondary and tertiary alkyl halides therefore primary alkyl halides undergo SN2 reaction.

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.
