Topic 3: Alkanes and cycloalkanes Flashcards
1
Q
Sources of alkanes
A
Natural gas, Petroleum, Coal
2
Q
Torsional strain
A
arises when atoms separated by three bonds are forced from staggered to eclipsed conformations
3
Q
Key reactions
A
- addition of H2 using a metal catalyst
- reduction of alkyl halides
- combustion
- halogenation (requires heat/uv)
4
Q
chair conformation
A
most stable conformation
c-c-c bonds 109.5
direction of axial or equatorial bonds alternates as you move from one ring to the next
5
Q
boat conformation
A
torsional strain created by the four sets of eclipsed H interactions
