During the course of an SN1 reaction, the intermediate species formed is:
Correct answer: A. A carbocation
- A. A carbocation
- B. A free radical
- C. A carbanion
- D. An intermediate complex
Explanation
When nucleophilic substitution takes place bond between C and X dissociates. Now there are only 3 bonds on carbon and carbon bears a positive charge. This is called 'carbocation'. The correct option is 'A'.

About Nucleophilic Substitution
Nucleophilic substitution replaces a leaving group in an alkyl halide when an electron-rich nucleophile attacks the carbon atom. The topic compares SN1 and SN2 mechanisms, including reaction conditions, substrate structure, solvent effects, nucleophile strength, carbocation formation and stereochemical changes, and distinguishes substitution from elimination.
