Alkenes
Unsaturated hydrocarbons with double bonds between two carbon atoms.
HYDRATION
________: In the presence of phosphoric (V) acid, 300 degrees celsius temperature and 60 atm pressure, alkenes react with steam to form alcohols.
Double bonds
________ are broken into single bonds.
BROMINATION
________: when ________ is added to an alkene, it immediately decolourises as the double bonds are broken and ________ atoms join the alkene.
Alkenes
________ can also be combusted.
An alkane can be broken in three ways using cracking
Making one alkane and one alkene, and one hydrogen, making two alkenes and hydrogen, making an alkane
Hydrogenation
Chemical reaction between molecular hydrogen and another compound or element, usually in the presence of a catalyst such as nickel.
Bromination
Chemical reaction that entails the introduction of one or more halogens into a compound.
Hydration
Hydration reaction is a chemical reaction in which a substance combines with water.
Addition reaction
A chemical reaction in which only one product is formed.
Saturated
Compounds with a single covalent bond between carbon atoms.
Unsaturated
Compounds with a double covalent bond between its carbon atoms.
Polyunsaturated
Compounds with more than one double covalent bonds between its carbon atoms.
