Explain SN¹ and SN² reaction in brief?
Answers
The SN2 reaction - A Nucleophilic Substitution in which the Rate Determining Step involves 2 components.
-SN2 reactions are bimolecular with simultaneous bond-making and bond-breaking steps.
-SN2 reactions do not proceed via an intermediate.
-SN2 reactions give inversion of stereochemistry at the reaction centre.
-Steric effects are particularly important in SN2 reactions.
For example:
Answer:
heya mate there's your answer
SN1 - REACTION :-
☆It is a Unimolecular Nucleophilic Substitution Reaction.
☆The rate of the reaction /concentration depends on only alkyl halides.
☆It will takes place in teritary alkyl halides very reactively.
☆Order of reactivity is,
3°>2°>1°>-CH3
☆It takes place in two step mechanism.
☆In first step carbocation is formed as intermediate. And in second step nucleophile attacks from both front abd back side.
☆ In this reaction recimic mixture will be formed. (Recimisation)
SN2 - REACTION : -
☆ It is a Bimolecular Nucleophilic Substitution Reaction.
☆The rate of the reaction/concentration depends on both alkyl halides and base.
☆It will takes place in primary alkyl halides very reactively.
☆Order of reactivity is,
CH3>1°>2°>3°
☆It takes place in only one step mechanism .
☆In this nucleophile attacks from back side.
☆In this reaction inversion takes place.
