Cracking is
Incomplete combustion of an alkene gives off
Alkenes are
When alkenes are burned with a lack of oxygen they produce
The second alkene is
Alkenes have fewer hydrogen atoms than their respective alkanes and are
In cracking, we first need to
Alkenes usually react via
Alkenes have at least one
When a C=C double bond in an alkene opens up to react with new atoms, it is known as
Incomplete combustion of an alkene gives a
The first alkene is
Splitting up long chain hydrocarbons is known as
The fourth alkene is
When long chain molecules split apart on the surface of the catalyst, it is known as
The atoms in a molecule that determine how the molecule typically reacts is known as
To work out the number of hydrogen atoms in straight chain alkenes, you
The third alkene is
Cracking uses a hot powdered
Vaporising hydrocarbons, mixing them with steam and heating them to a very high temperature is known as
Two hydrogen atoms can be added across the double bond of an alkene, resulting in a saturated alkane. This happens in the presence of a catalyst and is known as
When alkenes are burned in lots of oxygen they produce
