Flashcards in 11.5 Deck (14):
1

Name the 2 types of bond fission

Homolytic fission
Heterolytic fission

2

Define covalent bond

A shared pair of electrons between 2 atoms

3

How are covalent bonds broken?

Through either homolytic/heterolytic fission

4

Define homolytic fission

The breaking of a covalent bond where one of the bonded electrons goes to each atom, forming 2 radicals

5

What is a radical?

An atom with an unpaired electron

6

Define heterolytic fission

The breaking of a covalent bond where one of the bonded atoms takes both of the electrons from the bond, forming a cation and an anion

7

What is a positive ion called?

Cation

8

What is a negative ion called?

Anion

9

Define reaction mechanism

The sequence of bond breaking and bond-forming steps that shows the path taken by electrons during a reaction

10

What do curly arrows show?

The movement of a pair of electrons

11

What are the 3 types of reaction?

Addition
Substitution
Elimination

12

Describe an addition reaction

2 products join to form one product.
Often, unsaturated alkenes become a single, saturated compound.

13

Describe a substitution reaction

An atom is replaced by a different atom.

14

Describe an elimination reaction

Involves the removal of a small molecule from a larger one.
One reactant forms 2 products.
