Haloalkane: SN1 AND SN2 Mechanism

Substitution Nucleophilic unimolecular I.e.

SN1 MECHANISM

* SN1 reaction is easily possible in tertiary halides.

* SN1 reaction are carried out in polar protic solvents like water, alcohol, acetic acid, etc.

Mechanism

* Slow step has one reactant. So, it is called unimolecular.

* The configuration is Racemisation.

Substitution Nucleophilic bimolecular I.e.

SN2 MECHANISM

* SN2 reaction is easily possible in primary halides.

Mechanism

* In slow step there is reactant and nucleophile. So, it is called bimolecular.

* The configuration is inverted also called inverted mechanism.
