ln SN1 reactions, which of the following species is formed and consumed in the reaction?
Correct answer: D. Carbocation
- A. Transition state
- B. Intermediate
- C. Carbanion
- D. Carbocation
Explanation
In SN1 reactions, the rate-determining step involves the formation of a carbocation intermediate. The nucleophile then attacks the carbocation to complete the substitution. The other options are not formed and consumed in the reaction in the same manner as the carbocation. Therefore, option d is correct.

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.
