Alkenes
________ normally combust completely if theres enough oxygen.
Ethanol
________ and water have a higher boiling point then ethene so both condense whilst any unreacted ethene gas is recycled back into the reactor.
Molecules
________ formed are saturated, with the C= C carbons each becoming bonded to a halogen atom.
Water
________ is added across the double bond and an alcohol is formed.
carbon carbon double bond
The ________ will open up and add additional atoms on.
addition of bromine
The ________ to a double bond can be used to test for alkenes.
Alkenes + oxygen
carbon + carbon monoxide + carbon dioxide + water(+energy)
What do alkenes burn with
Smokey yellow flame
Incomplete combustion left hand side
Alkene and oxygen
Incomplete combustion right hand side
Carbon, carbon monoxide, carbon dioxide and water
Hydrogen reaction with alkenes
Hydrogenation, forms equivalent saturated alkene
Steam reaction with alkenes
Water added across double bond makes alcohol formed
Halogens react
Splits double bond and halogen bonds onto each carbon
Halogens
Group 7
Addition reactions
New atoms are added
Functional group
A group of atoms on a molecule that determine how that molecule will react
