Making Halogenoalkanes Flashcards
What is a reaction mechanism?
A series of steps that shows you how something/substance is going to react
What does a double headed arrow show in organic chemistry
It shows movement of paired electron
What is a free radical
Any atom with an unpaired electron
What is a substitution reaction?
A species takes the place of part of a molecule
What happens at the initiation step of the free radical substitution
Free radicals are made.
UV
Cl2 —-> 2Cl•
UV acts as a catalyst
What happens at the propagation step of the free radical substitution
Free radicals make more free radicals
Cl• + CH4 —-> HCl + •CH3
•CH3 + Cl2 —-> CH3Cl + Cl•
What happens at the termination step of the free radical substitution
Free radicals react with each other and make no more free radicals.
•CH3 + •Cl —-> CH3Cl
