Electrophilic Substitution of benzene Flashcards
1
Q
How does Nitration of Benzene occur?
A
Benzene reacts with NO2+, the elctrophile (from HNO3) to form
In presence of con. H2SO4 catalyst, 50-55 degrees and conc HNO3.
2
Q
What happens when the temperature is too high in nitration of benzene?
A
Polynitritation occurs. These are explosive
3
Q
What is needed for the monobromination of benzene?
A
FeBr3/AlBr3 and Br2
3
Q
How is the electrophile formed for monobromination of benzene?
A
FeBr3/AlBr3 + Br2 —> Br+ + FeBr4-
