Q
How is homolytic fission different from the formation of ions?
A
When the bond splits it forms neutral radical whereas with ions, electrons are lost or gained.
2
Q
Initiation,propagation, termination
A
The three main reactions that occur in a free radical chain reaction.
3
Q
Why is UV light important in homolytic fission?
A
It has sufficient energy to break the covalent bond, and start initiation.
4
Q
In what order do the stages in free radical chain reaction occur?
A
Simultaneously
5
Q
What stage never produces free radicals in homolytic fission?
A
Termination
6
Q
