You will probably find that bromobenzene either doesn't react at all or reacts slowly via both the SN1 and the SN2 mechanisms. Try to explain this on the basis of the strength of a carbon(sp2)-bromine bond compared to the strength of a carbon(sp3)-bromine bond.

Step 1
Bromobenzene has a carbon-bromine bond where the carbon is sp2 hybridized, as it is part of an aromatic ring. In contrast, alkyl bromides have a carbon-bromine bond where the carbon is sp3 hybridized. Show more…

1. How does an SN1 reaction differ from an SN2 reaction? Explain in terms of the substrate, nucleophile, and mechanistic steps. 2. Explain the stereochemistry of the SN2 attack. 3. What substrates react faster in SN2 reactions, tertiary or primary? Why? 4. Identify the substrate and nucleophile in the reactions below, then draw the mechanism and products for each reaction:
