11.5 Introduction of reaction mechanisms Flashcards
1
Q
Homolytic fission
A
-the covalent bond breaks and the electrons are evenly shared between the bonding atoms forming radicals
2
Q
Heterolytic fission
A
-covalent bond breaks and one of the bonding atoms takes both electrons from the covalent bond from oppositely charged ions.
3
Q
Curly arrows
A
-Shows the movement of electron pairs when bonds are broken or made.
4
Q
Types of reactions
A
-Addition reactions
-Substitution reactions
-Elimination reactions
5
Q
Define addition reactions
A
Two reactants join to form one product.
6
Q
Define Substitution reactions
A
An atom or group of atoms is replaced by an atom or group atoms.
7
Q
Define Elimination reactions
A
Removal of a smaller molecule from a larger one
-Usually forms two products
