Arenes Quiz

UNIT F324: Rings, Polymers & Analysis sub topic 'Arenes' quiz.

This quiz is all about the structures, reactivity and mechanisms of arenes.

?
What is benzene's molecular formula?
C6H6
1 of 9
What shape does a benzene molecule make?
Planar
2 of 9
What is the shape about each C atom in the benzene molecule?
Trigonal planar
3 of 9
Benzene's electron rich π-bond means that it attracts WHAT?
Electrophiles (electron pair acceptor)
4 of 9
Define electrophilic substitution (specifically for benzene).
A H atom on the benzene ring is replaced by an electrophile. The electrophile is attracted to the electron-rich π-bond, where it accepts a pair of electrons from the π-bond to form a new covalent bond with a C atom of the ring.
5 of 9
What are the reagents and conditions needed for the nitration of benzene?
Reagents: Concentrated nitric acid and benzene, Conditions: Concentrated sulphuric acid catalyst, heat under reflux at 50°C
6 of 9
In nitration of benzene, what acts as the electrophile?
NO2 +
7 of 9
What are the reagents and conditions needed for the chlorination of benzene?
Reagents: Chlorine and benzene, Conditons: Halogen-carrier catalyst (e.g. iron(III) chloride) and heat under reflux.
8 of 9
Since phenol is an acid, phenol can react with basic substances to form salts. What is the name used for phenol salts?
Phenoxide salts
