Alkanes Flashcards
1
Q
Free Radical (Radical)
A
species containing an unpaired electron
2
Q
Homolytic fission
A
- covalent bond breaks
- one of the bonded electrons goes to each atom
- produces 2 free radicals
3
Q
Initiation
A
- first step in free radical substitution
- free radicals are made by UV radiation
4
Q
Propagation
A
- second step in free radical substitution mechanism
- two repeated steps where new free radicals are made
5
Q
Saturated
A
compound containing C-C bonds
6
Q
Structural Isomers
A
- Molecules with the same molecular formula
- but with different structural formula (arrangements of atoms)
7
Q
Substitution Reaction
A
- A reaction where an atom / group of atoms
- is replaced with a different atom / group of atoms
- (2 become 2 etc.)
8
Q
Termination
A
- final step in free radical substitution
- 2 radicals combine to form a stable
molecule
