SN2 reactions are _ ?

Correct answer: B. Nucleophilic bimolecular substitution reactions

  • A. Nucleophilic unimolecular addition reactions
  • B. Nucleophilic bimolecular substitution reactions
  • C. Nucleophilic bimolecular addition reactions
  • D. Nucleophilic unimolecular substitution reactions

Explanation

SN2 (Substitution Nucleophilic Bimolecular) reactions are a type of nucleophilic substitution reaction that occurs when a nucleophile attacks a substrate molecule that has a leaving group attached to it. In an SN2 reaction, the nucleophile displaces the leaving group in a single step. The reaction proceeds through a transition state in which the nucleophile and the leaving group are both partially bonded to the substrate molecule.

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.
