Which of the following is formed during SN1 reactions?
Correct answer: C. Tertiary carbocation
- A. Secondary carbocation
- B. Primary carbocation
- C. Tertiary carbocation
- D. Methyl carbocation
Explanation
In step 1 of the SN1 reaction mechanism, the C-Br bond breaks and Br departs with the bonding electron pair to produce a tertiary carbocation and bromide anion Br-. This step only involves a highly endothermic bond-breaking process, and this is the slowest step in the whole mechanism.

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.
