SN1
๐ 1. substitution nucleophilic unimolecular.
๐ 2. Two step process
1st step = carbocation intermediate formed in step 1.[stable]
2nd step = nucleophilic attack, left and right in carbocation
๐ 3. * 1st step =slow
*2nd step=fast
๐ 4. Racemic mixture form in SN1 reactoin .[50-50%]
๐ 5. Rate= k1 [substate]
Ex=
SN2
๐ 1.Substitution nucleophilic bimolecular.
๐ 2.One-step reaction.
* Transition state forms.
๐ 3. Fast reaction in SN2 reaction .
๐ 4. 100% inversion mixture in SN2.
๐ 5. Rate=k [Nu][R-LG].
