1
Q

How could you explain the arrangement of the 6 extra electrons in the arrangement of benzene

A

Delocalised and in P orbitals either above or below the carbons

2
Q

What word is used to describe the stability of Benzene

A

Aromatic stability

3
Q

What organic species attacks a benzene ring, state the mechanism for this reaction too

A

1 - Electrophile

2 - electrophilic substitution

4
Q

What is the generalised rule for naming aromatic compounds

A

The group coming off the benzene ring becomes the prefix and “benzene” becomes the suffix. Locations can be determined from the first point if there is more than 1 functional group on the benzene ring

5
Q

What is the product which is substituted off of the benzene ring in a electrophilic substitution

A

A hydrogen from the benzene ring is lost forming a H+ ion and is replaced with the Electrophile

6
Q

Name the Electrophile ion which attacks a benzene ring during nitration

A

Nitronium ion

7
Q

Write the equation for forming the NO2+ ion from H2SO4 and HNO3

A

H2SO4 + HNO3 –> H2NO3+ + HSO4-

H2NO3+ –> NO2+ + H2O

8
Q

What is the name of a benzene ring with a nitronium ion substituted in

A

Nitrobenzene

9
Q

Give an industrial use of nitration

A

The formation of explosives such as TNT

10
Q

State the general formula of a benzene ring

A

C6H6
