25. BENZENE AND ITS COMPOUNDS Flashcards
1
Q
Why do benzene and ethene differ in their reactions with bromine
A
delocalised ring of electrons in benzene is stable so is reformed
electrons in ethene pi bond are localised so it is available for attack by electrophile
2
Q
Why does benzene not get halogenated easily
A
delocalised ring of electrons in benzene is stable
3
Q
Why do alkenes get brominated easily
A
pi bond electrons are localised and are a centre of negative charge
4
Q
When do electrophilic substitution/addition reactions happen easily
A
when the electrons are localised and there is a centre of negative charge
