During SN1 mechanism, nucleophile can attack on the halogen carbon?
Correct answer: C. From both sides
- A. From opposite side of the leaving group
- B. From front of the leaving group
- C. From both sides
- D. None of these
Explanation
Option c is correct. In SN1 reactions, since the nucleophile attacks the planar carbocation intermediate, it can indeed approach from either side, leading to a mixture of products with both inversion and retention of configuration. This phenomenon is known as racemization, resulting in a racemic mixture of stereoisomers.

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.
