In SN1 reactions, the correct order of reactivity of alkyl halide is?
Correct answer: B. Tertiary>secondary>primary
- A. Primary>secondary>tertiary
- B. Tertiary>secondary>primary
- C. Secondary>primary>tertiary
- D. Primary>tertiary >secondary
Explanation
Tertiary > Secondary > Primary (Correct)Explanation: Tertiary carbocations are the most stable due to inductive and hyperconjugation effects, making tertiary alkyl halides the most reactive in SN1 reactions.

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.
