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