An SN2 reaction at an asymmetric carbon of a compound always gives:
Correct answer: B. A product with opposite optical rotation
- A. An metamerism of the substrate
- B. A product with opposite optical rotation
- C. A mixture of diastereomers
- D. A single stereoisomer
- E. The same product
Explanation
An SN2 reaction at an asymmetric C of a compound always gives a product with opposite optical rotation. An SN2 reaction at an asymmetric C of a compound involves inversion of configuration.

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.
