Answer 2

Answer:

Explanation:

Sn1

• It is Unimolecular
• It is First Order Reaction
• Generally carried out in polar protic solvents like :- water , alcohols and acetic acids
• Takes place in two steps through carbocation as the intermediate
• Rate of Reaction : 3° > 2° > 1° > CH₃ halides
• Greater the stability of carbocation faster will be the reaction
• Tends to proceed with weak nucleophiles , eg :- CH₃OH , H₂O
• Both retention and inversion of configuration takes place .

Sn2

• It is Bimolecular
• It is Second Order
• Carried out in polar aprotic solvents like :- acetone , DMSO , acetonitrile or DMF
• Takes place in one step through transition state
• Rate of Reaction : CH₃ > 1° > 2° > 3° halides
• Less the steric hindrance in transition state , faster will be the reaction
• Tends to proceed with strong nucleophiles , eg :- CH₃O⁻ , CN⁻

• Inversion of configuration takes place ( Walden Inversion )
