Which of the following best describes the structure of benzene?
a hexagonal ring of carbon atoms
a pentagonal ring of carbon atoms
a branched chain of carbon atoms
a linear chain of carbon atoms
|
According to the delocalised model of benzene, the electrons are...
localised on individual carbon atoms
absent from the structure
delocalised over the whole ring
fixed between specific atom pairs
|
How does each carbon atom in benzene contribute to the π-bonding system?
by sharing two electrons from its 2p orbital
by sharing two electrons from its 2s orbital
by sharing one electron from its 2s orbital
by sharing one electron from its 2p orbital
|
Benzene prefers to undergo...
elimination reactions
substitution reactions
addition reactions
rearrangement reactions
|
The difference in reactivity between benzene and alkenes can be explained by...
the localisation of electrons in alkenes
the absence of a π-bond in alkenes
the delocalisation of electrons in benzene
the presence of a σ-bond in benzene
|
In the delocalised model of benzene, the -orbitals overlap around the ring, forming a delocalised system of 6 electrons.
|
The remarkable stability seen in benzene is attributed to the of electrons above and below the hexagonal ring.
