Reactions of benzene Flashcards
1
Q
Why do alkenes react with bromine
A
C=C is a localised area of high electron density - attracts an electrophile
2
Q
How can you make benzene react with bromine
A
hot benzene and UV light
3
Q
why doesn’t benzene react with bromine
A
The benzene ring is stable and the negative charge is spread out - unwilling to undergo addition reaction
4
Q
What mechanism does benzene undergo
A
Electrophilic substitution
5
Q
What is nitration
A
Reacting warm benzene with concentrated nitric acid (HNO3) and (concentrated sulfuric acid acts like a catalyst)
6
Q

A
Nito(NO2) benzene and water
