Which statement is incorrect about nucleophilic substitution reaction:
Correct answer: B. Leaving nucleophile must be stronger than incoming nucleophile
- A. Incoming nucleophile must be stronger than the leaving one
- B. Leaving nucleophile must be stronger than incoming nucleophile
- C. Tertiary alkyl halides generally give SN1 reactions
- D. SN2 is a single step mechanism
Explanation
SN reactions are favoured by a good leaving and stronger incoming group. Leaving nucleophile must be weaker than the incoming nucleophile.

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.
