Question 24

3 types of isomerism

Answer 24

1. functional group
2. positional isomerism
3. chain isomerism

Question 25

2 ways covalent bonds can break

Answer 25

1. homolytic fission
2. heterolytic fisson

Question 26

how are electrons shared in homolytic fission?

Answer 26

both atoms get one electron from the bond

Question 27

how are electrons shared in heterolytic fission?

Answer 27

one atom gets both electrons from the bond

Question 28

rules in mechanisms

Answer 28

1. atom with unpaired electron = radical
2. formation of bond = curly arrow
3. one electron = half curly arrow
