What are some differences between alkanes and alkenes?
Alkanes are saturated (they have a single covalent bond) whilst alkenes are unsaturated (they have a double covalent bond). For alkanes: 2n+2 and for alkenes: 2n

What conditions are needed for addition polymerisation?
You need high amounts of pressure and a catalyst.

Why does an alkene react with bromine water, unlike an alkane?
Due to their weak double bond, an alkene can decolourise the bromine water and form a dibromo compound.
