During the SN1 reactions, the fast reaction involves:
Correct answer: D. Attack of nucleophile
- A. Breakage of covalent bond
- B. Formation of carbocation
- C. Transition state
- D. Attack of nucleophile
Explanation
The nucleophile has a negative / partially negative charge and it readily attacks the carbocation in SN1 reactions (which has a positive charge) This is the fast step of the reaction.

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.
