1
Q
What is the simplest aromatic hydrocarbon?
A
Benzene (C₆H₆)
2
Q
Explain the stability of the benzene ring.
A
delocalisation of electrons in the conjugated system
3
Q
What is a phenyl group
A
A benzene ring in which one hydrogen atom has been substituted by another group is known as the phenyl group.
The phenyl group has the formula –C₆H₅
4
Q
What type of reactions do benzene rings typically take part in?
A
Electrophilic substitution reactions.
5
Q
Give an example of a reaction of a benzene ring. (include reagents).
A
- halogenation: benzene + halogen -> halobenzene; AlCl3 or AlBr3 catalyst depending on halogen being added
- alkylation: beneze + haloalkane -> alkylbenzene; AlCl3 catalyst
- nitration: benzene + concentrated sulfuric acid and concentrated nitric acid -> nitrobenzene
- sulfonation: benzene + concentrated sulfuric acid -> benzenesulfonic acid
