Alkanes Flashcards
1
Q
Alkanes are saturated or unsaturated
A
Saturated (no double bond)
2
Q
Describe fractional distillation
A
vaporise the mixture, the vapour rises. Highest boiling point/ longest chain hydrocarbons condense near bottom of fractionating column and shorter lenght/lowest boiling point condense near the top. It has a temperature gradient cooler at top and hotter at bottom. Mixture condenses at different temperatures because different chain length have different boiling points
3
Q
conditions and products for thermal cracking and products
A
1000 degrees
70 atm of pressure
produces mainly alkenes
4
Q
conditions and products for catalytic cracking
A
Zeolite catalyst
450 degrees
mainly produces aromatic hydrocarbons
5
Q
Catalyst in catalytic converter
A
Platinum
