OZ 3 Radiation And Radicals Flashcards
What is bond breaking sometimes called?
Bond fission.
What does bond fission involve?
Redistribution of electrons in a covalent bond.
What are the two types of bond fission?
Heterolytic fission and homolytic fission.
What is heterolytic bond fission?
Where both of the shared electrons go to just one of the atoms when the bond breaks.
What happens to the atoms in heterolytic fission?
The atom with both electrons becomes negatively charged and the other becomes positively charged.
When is a heterolytic fission bond common?
When a bond is already polar.
What is homolytic fission?
Where one of the two shared electrons goes to each atom.
How do you write a radical?
A dot beside the atom.
Why do radicals have no charge?
They have the electronic structure they had before they shared their electrons to form the bond.
What does the unpaired electron from a radical have the tendency to do?
Pair up again with another electron from another substance.
When are radicals most commonly formed?
When the bond being broken is non-polar.
