Sn1 reaction(Unimolecular nucleophilic substitution reaction): It is a two-step reaction that involves first order kinetics. In the first step carbon and halogen bond breaks heterolytically to form carbocation in the presence of nucleophile. In the second step nucleophile attacks on the carbocation. First step is slow, hence it is the rate determining step in this reaction.
Difference b/w sn1 and sn2:
- Sn1 is two step process whereas sn2 is one step process.
- Sn1 follows first order kinetics whereas sn2 follows second order kinetics.
- rate of sn1 depends on concentration of substrate whereas in sn2 it depends on both concentration of substrate as well as nucleophile.
- Sn1 makes racemic mixture of product whereas sn2 involves walden inversion.
- Sn1 has carbocation intermediate whereas sn2 has trigonal bipyramidal intermediate
Difference b/w alcohols, phenols and ethers:
Alcohol: It is the product which we get when a saturated carbon atom bonds to hydroxyl group(-OH).
Phenol: When (-OH) group replaces hydrogen of benzene.
Ether: It is a product when oxygen group bonds to two aryl or alkyl groups.
