Benzene aromatic chemistry

Question 1

What are aromatic compounds?

Answer 1

= includes one or more ring of 6 carbon atoms, with delocalised bonding

Question 2

What is the structure of benzene?

Answer 2

= C6H6
= hexagonal ring
= one hydrogen bonded to each carbon atom
= has delocalised atoms represented as a ring
=

Question 3

How reactive is benzene?

Answer 3

= benzene does not undergo addition reactions because the delocalised system will break- unstable
= most reactions involve subsituting one hydrogen for another atom or a group of atoms
= has a high electron density
= electrophilic subsitutuin reactions

Question 4

Is benzene toxic?

Answer 4

= is a carcinogen, cancer causing molecules
= methyl benzene is less toxic as methyk sude group releases electrons into delocalised syetm making it more attractive to electrophiles
