Which of the following is correct about SN2 reactions:
Correct answer: D. All of these
- A. Breakage of C-X and formation C-Nu bonds are simultaneous
- B. Inversion of the configuration of the alkyl halide molecule
- C. 2nd order kinetics
- D. All of these
Explanation
Option A, B, and C are all correct, all the 3 options represent the characterstic features of SN2 reactions. Breakage of C-X and formation C-Nu bonds both occur in the same step. Inversion of the configuration of the alkyl halide molecule is 100%. Order of reaction is 2.

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.
