ring strain trends
|
zero for cyclohexane. increases with fewer or greater number of carbons. starts to decrease again with nine-carbon ring structures

|
combustion of alkanes
- what is required? - what are the products? - what type of reaction is it? |
Required : oxygen and high activation energy (high temps)
Products : CO2, H2O, and HEAT Type : radical |
|
|
What are the three steps of halogenation? Stability?
|
1) Initiation: diatomic halogen is homolytically cleaved by heat or UV light --> free radicals
2) Propagation : Radical removes hydrogen from alkane resulting in alkyl radical. Alkyl radical reacts with diatomic halogen creating an alkyl halide and new halogen radical. continues indefinitely unless terminated. 3) termination : two radicals bond, or radical bonds to wall of container follows carbocation stability order. 3 > 2 > 1 > methyl |
|
|
as reactivity of a halogen increases, the selectivity (increases/decreases)
|
decreases
