Bond Fission Flashcards
What is homolytic fission?
Where each atom takes a bonding electron to form 2 radicals, when breaking a covalent bond.
What is heterolytic fission?
Where the more electronegative atom takes both bonding electrons to form a negative ion and leave a positive ion, when breaking covalent bond.
What is a radical?
A reactive chemical species with an unpaired electron.
What does a reaction equations tell us?
The amount of reactants and products in the reaction.
What does a reaction mechanism tell us?
How the reaction actually takes place.
What do curly arrows show in a reaction mechanism?
The movement of electrons.
What does singlehead curly arrows show?
The movement of one electron.
When does the movement of one electron occur?
During homolytic fission, when two radicals terminate, and when a radical and covalent compound propagate.
What do double headed curly arrows show?
The movement of a pair of electrons.
When does the movement of a power of electrons occur?
During heterolytic fission, or an addition reaction.
What reactions are curly arrows a feature in?
Addition reactions, substitution reactions, and elimination reactions.
