In which of the following reactions, rate of reaction is not affected by increasing concentration of nucleophile?
Correct answer: C. SN1
- A. SN2
- B. E2
- C. SN1
- D. None of these
Explanation
The SN1 mechanism is a two-stepmechanism in which the rate is dependent on the halogenoalkane and not the nucleophile. Hence, no matter how much we increase the reactant that is the nucleophile it will have no effect on the rate.

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.
