Organic Lecture Series Mechanisms SN2
• An energy diagram for an SN2 reaction. There is one
transition state and no reactive intermediate. 5 Organic Lecture Series Mechanisms SN1
• Bond breaking between carbon and the
leaving group is entirely completed
before bond forming with the nucleophile
begins.
• This mechanism is designated SN1 where
– S = substitution
– N = nucleophilic
– 1 = unimolecular (only one species is involved
in the rate-determining step) 6 Organic
