Which of the following is formed preferably during SN1 reactions?
Correct answer: C. Tertiary carbocation
- A. Secondary carbocation
- B. Primary carbocation
- C. Tertiary carbocation
- D. Methyl carbocation
Explanation
In SN1 reactions, the carbocation formed is stabilized by adjacent alkyl groups. Tertiary carbocations, with three alkyl substituents, are more stable than primary or secondary carbocations due to hyperconjugation and inductive effects. Therefore, option c 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.
