During SN1 mechanism, nucleophile can attack on the halogen carbon?
Correct answer: C. From both sides
- A. From opposite side of leaving group
- B. From front of leaving group
- C. From both sides
- D. None of these
Explanation
During an SN1 mechanism, the nucleophile can attack the halogen carbon from both sides as the intermediate carbocation formed is sp2 hybridized and planar, allowing for equal access from both sides. The other options are incorrect.

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.
