Alkanes And Alkenes Flashcards
1
Q
Formula for Alkanes
A
CnH2n+2
2
Q
First 6 alkanes in order
A
Methane Ethane Propane Butane Pentane Hexane
3
Q
What type of bond is an alkane
A
Simple covalent
4
Q
In alkanes, what’s the boiling point and why
A
Really low boiling points as there are weak intermolecular forces of attraction
5
Q
Are alkanes saturated
A
They are saturated this means that carbon atoms are joined to each other by single bonds
6
Q
What’s cracking?
A
Where long Alkanes are vaporised and passed over hot catalyst OR mixed with steam at high temp to produce shorter alkanes and Alkanes.
7
Q
Are alkenes saturated
A
No because there is a double bond
8
Q
Key points of making ethanol from fermentation
A
Sugar = ethanol + CO2 Renewable Batch process Slow Impure product Catalyst ? Green?
9
Q
Key points of making ethanol from hydration
A
Ethene + steam = ethanol Non renewable Fast Continuous Pure product Catalyst ? Green ?
