Which of the following best describes the structure of benzene?
a linear chain of carbon atoms
a hexagonal ring of carbon atoms
a branched chain of carbon atoms
a pentagonal ring of carbon atoms
|
In the Kekulé model of benzene, the bonds are represented as...
a combination of single, double, and triple bonds
alternating single and double bonds
all single bonds
all double bonds
|
According to the delocalised model of benzene, the electrons are...
absent from the structure
fixed between specific atom pairs
localised on individual carbon atoms
delocalised over the whole ring
|
Which of the following is true about the stability of benzene?
it is exactly as stable as predicted by the Kekulé model
it is more stable than predicted by the Kekulé model
it is less stable than predicted by the Kekulé model
|
Benzene prefers to undergo...
substitution reactions
rearrangement reactions
addition reactions
elimination reactions
|
The difference in reactivity between benzene and alkenes can be explained by...
the absence of a π-bond in alkenes
the presence of a σ-bond in benzene
the delocalisation of electrons in benzene
the localisation of electrons in alkenes
|
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.
|
How does each carbon atom in benzene contribute to the delocalised ring system?
by sharing one electron from its 2p orbital
by sharing one electron from its 2s orbital
by sharing two electrons from its 2p orbital
by sharing two electrons from its 2s orbital
