Answer #1

The SN1 reaction= A Nucleophilic Substitution in which the Rate Determining Step involves 1 component.

1.SN1 reactions are unimolecular, proceeding through an intermediate carbocation.
2.SN1 reactions give racemization of stereochemistry at the reaction centre.
3.The first step is slower and therefore determines the rate.
4.Neighbouring group participation is SN1 reactions can be important

The SN2 reaction -=A Nucleophilic Substitution in which the Rate Determining Step involves 2 components.

1.SN2 reactions are bimolecular with simultaneous bond-making and bond-breaking steps.
2.SN2 reactions do not proceed via an intermediate.
3.SN2 reactions give inversion of stereochemistry at the reaction centre.
4.Steric effects are particularly important in SN2 reactions
