Just as detectives investigate a crime after it has taken place and arrive at a reasonable prediction about how the crime may have occurred, similarly organic chemists predict by a number of laboratory techniques using sophisticated instrumentation how an organic Reaction may have taken place.
Elimination, rearrangement Elimination [12] TS of slow step • Factors to decide whether S N 1 or S N 2 : Any factors that affects the energy of activation of a given type of reaction will affect the rate and / or mechanism. These factors are useful to decide whether S N 1 or S N 2 occurs : 1. Electronic effect . 2. Steric effect . 3.
