Question

What is sn1 and sn2 reaction mechanism?

Answer 1

i hope ans. is right
.

Answer 2

Hii dear,
Both SN1 & SN2 are types of nucleophilic substitution.

# SN1 reaction -
- Rate determining step involves 1 component in SN1 reaction.
- These reactions are usually unimolecular.
- Reaction proceeds through formation of an intermediate.
- There is racemization of stereochemistry at the reaction centre.
- The first step is slower and therefore determines the rate.

# SN2 reaction-
- Rate determining step involves 2 components in SN2 reaction.
- These reactions are bimolecular.
- Reactions do not involve intermediate formation.
- There is inversion of stereochemistry at the reaction centre.

Hope this ia useful...
