3.6 Aromatics and Amines Flashcards
1
Q
Formula of benzene
A
C6H6
2
Q
Describe the structure of benzene
A
Planar cyclic
Each carbon forms single covalent bonds
Final electron forms ring of delocalised electrons
3
Q
How is benzene draw
A
Hexagon with circle in centre
4
Q
Experimental evidence for stability of benzene
A
Its enthalpy of hydrogenation is less exothermic than expected so more energy is require to break its bonds
5
Q
Ways to name aromatic compounds
A
Suffix -benzene is the ring if the main functional group
Prefix Phenyl- if the ring is not the main functional group
6
Q
What does the benzene ring attract?
A
Electrophiles as it has a high electron density
7
Q
What kind of reactions does benzene undergo
A
Electrophilic substitution
