Chapter 7: 7.2 Electrophilic Aromatic Substitution Reactions Overview

Question 1

What are EAS reactions? What are they useful for?

Answer 1

Electrophilic Aromatic Substitution reactions
* Vital tool for functionalizing aromatic rings
* Useful to make complex molecules

Question 2

What do EAS reactions rely on?

Answer 2

Most aromatic rings are relatively electron-rich
* Will attack a suitable electrophile via a standard addition-type mechanism

Question 3

True or False:

Benzene is reactive

Answer 3

False, benzene is aromatic and very stable (unreactive)

Question 4

How do we force a benzene ring to do chemistry?

Answer 4

Use a catalyst to activate the benzene ring
