SN2 reactions are _?
Correct answer: C. Single step reactions
- A. Two step reactions
- B. Multistep reactions
- C. Single step reactions
- D. None of these
Explanation
SN2 reactions are single step reactions. The correct answer is C. In SN2 (substitution nucleophilic bimolecular) reactions, the nucleophile directly attacks the substrate in a single concerted step, leading to the displacement of the leaving group. This distinguishes SN2 reactions from SN1 reactions, which involve multiple steps.

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.
