The product in SN2 reaction is formed with _.
Correct answer: A. Inversion in configuration
- A. Inversion in configuration
- B. Retention in configuration
- C. 50% retention in configuration
- D. 50% inversion in configuration
Explanation
The question deals with knowing the mechanism of SN2 reaction and evaluating the inversion of the end product in relation to the initial reaction. In SN2 reaction, the nucleophile attacks from the other side of the attached nucleophile since it hinders the attack and for the nucloephile to attack from the backside of the carbon is easy. Thus, the product formed has a stereochemical position opposite to that of the leaving group orignally occupied. 50% inversion and 50% retention takes place in SN1 reaction, marking both option C and D incorrect. According to the above explanation, option A is valid, since it mentions the inversion of configuration seen in 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.
