What is the value of molecularity and order of SN2 reactions?
Correct answer: B. 2 and 2
- A. 2 and 1
- B. 2 and 2
- C. 1 and 1
- D. 1 and 2
Explanation
For SN2 reactions: Molecularity is second-order (bimolecular) because the reaction involves a collision between a substrate molecule and a nucleophile. The order of reaction is 2 with respect to both the substrate and the nucleophile, resulting in an overall reaction order of 2. Therefore, option b is correct.

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.
