Question

Explain the Reaction of ROH with PBr₃—An S_N2 Mechanism

Expert Solution

Concept:

A Ncleophilic Substitution reaction in which the rate determining step involves 2 components.

1. S_N2 reactions are bimolecular with simultaneous bond formation and bond breaking steps. 2. S_N2 reactions do not proceed via an intermediate. 3. S_N2 reactions give inversion of stereochemistry at the reaction center. 4. Steric effects are particularly important in S_N2 reactions.
