Aromatic Compounds Flashcards
1
Q
Why does benzenes bond lengths prove the kekule structure is wrong
A
As they are different lengths
2
Q
What does the enthalpy of hydration of benzene and kekule show
A
That the hydration of kekule is far less exothermic and it takes more energy to break benzenes bonds and thus it is more stable thank kekule due to delocalised ring
3

6
Q
What is a use for the nitration of benzene
A
To produce explosives
7
Q
What is required for the hydration of nitro benzene
