Card preview (11)
What is the first thing that happens in the propagation stage?
A chlorine atom attacks a methane molecule to form hydrogen chloride and a species called a methyl free radical
What does a chlorine atom attack?
A methane molecule
What is formed when a chlorine atom attacks a methane molecule?
A hydrogen chloride is formed and a species called a methyl free radical
What forms a hydrogen chloride and a methyl free radical?
A chlorine atom attacking a methane molecule forms them
What is a free radical?
A free radical is simply any atom or group of atoms with an unpaired electron
What is the symbol for a free radical?
It shows the unpaired electron as a dot
What does propagation always involve the use of free radicals to do?
To produce another free radical
Are free radicals very reactive or not very reactive?
They are very reactive
Why are free radicals not very reactive?
As they do not have a full octet of electrons in their outer energy level
What do free radicals do to the human body?
They are believed to be related to the process of aging
